Project 3: Market Analysis (Week 2)

In this first map submission, there is a market comparison for the two existing stores to distinguish household patterns for book sales and the relative drive time to arrive at the store. The Steiner location will be used as a model store to perform the comparative analysis to select the best of the two proposed locations for the newest addition to the Best Books Store family.



The three prospective locations are identified in the following map.

Week 4: Marin City, CA Greenspace Study

The attached maps present imagery of Marin City, CA that has been reclassified to depict the regions throughout the city that are dominated by trees, grass, and impervious layers. The first map shows the location of Marin City by providing inset maps of both Marin County and the group of San Francisco Bay Area Counties.



The second map presents just the Marin City data frame that was generated in ArcInfo 9.3.1 so the classification can be more clearly evaluated or examined.

Process Summary for
Prepare I: Air Pollution, Asthma, and Race in the San Francisco Bay Area

September 7, 2010


Objective:

To gather data from typical public-access sites that will be incorporated into a comprehensive GIS that will elucidate the relationship between air quality, human health, and race in the San Francisco Bay Area counties.

Data Gathering:

Demographic data was parsed out from the US Census 2000 website,(http://factfinder.census.gov/servlet/datasetmainpageservlet) to identify the racial composition of the San Francisco Bay Area counties.

Asthma hospitalization rates (sorted by race) were manually transcribed from the California County Asthma Hopitalization Chart Book (Data from 1998-2000), California Department of Health Services. 9/03.

Air quality data (ozone and particulate matter) were both downloaded from the Bay Area Air Quality Management District (BAAQMD)(http://www.baaqmd.gov)

Data Handling:

The downloaded data were copied into separate MS Excel spreadsheets.
The resulting spreadsheets were modified to a format that would be
suitable to merge into the attribute table of existing shapefiles provided
by Ms. Trisha Holtzclaw. FID numbers were incorporated into the
spreadsheets that would be matched with the pre-existing FID values in
the shapefiles.

Documentation:

The metadata for the spreadsheets were updates in ArcCatalog using the
metadata file editor function. In the meantime, I realized that it would be
most appropriate to first merge the demographic and asthma
hospitalization rate files because these data would ultimately be merged
with the county shapefile (polygons), and the ozone and particulate
should be merged because they would be joined with the air monitoring
stations layer (point shapefile). Once these spreadsheets were
appropriately merged, then the metadata files could be updated.

Future Expectation:

The collected and modified data will be examined and incorporated into
a comprehensive GIS that will help us better understand patterns and
correlations of air quality, race, and human health in the San Francisco
Bay Area counties.

Week 5: LIDAR Image of Pensacola, FL

Below is a re-worked LIDAR image of an area in Pensacola, FL.

Week 4: Remote Sensing - Classification

Attached are two maps of the Germantown, MD images after recoding and reclassification from an original image provided by Ms. Trisha Holtzclaw. Histogram values that resulted from the reclassification step are included in the images' legends.





Below is an explanation of the reason that there are two submitted maps. One presents the appropriate RGB 5,4,3 color code...the other shows the classes grouped based on similarity (i.e. all urban/residential grouped as one)...however, the colors were manually altered because the RGB 5,4,3 was not informative and did not distinguish dissimilar land characteristics.

Week 3: Remote Sensing (Orthorectification)

This week's map presents an orthorectified image of Pensacola, Florida. The process of orthorectification was based off of the coordinates of a USGS Quad topo map of Pensacola. Included is a copy of the table that shows the RMSE (root mean square error) associated with this calibration. The total RMSE was 0.54 pixels.

ERDAS is a ridiculously cryptic software...there is NO support for the user of the software, and for those who do not have the most current operating system, XPS is not a user-friendly file format.




Total RMSE = 0.54 pixels

Week 2: Remote Sensing (Bands Analysis)

The Week 2 laboratory assignment involved further investigation of the tools of band analysis and selection. Three maps were generated that related to specific pixel values. In this case they corresponded to a lake, a limestone quarry, and an estuary. Click the links to view these maps.

Week 12: SAT Scores Final Project

Attached is the figure (including caption) that I generated mindful of an general readership audience of a typical newspaper. This figure would prevent a standard black-and-white printing because of the critical need for color, however, this figure offers a suitable color scheme for a standard three-color press. I had to download a shapefile from the U.S. Geological Survey because the one that the class used for the Chloropleth Map assignment did not have any georeferencing (i.e. when I tried to insert a legend, it indicated that the country was approximately 2 miles long and the shapefile would not accept a new coordinate system). Further details about this figure will be submitted directly for review.



Here is my proposed caption because the one on my map is more than 50 words:
The one on the map is probably more suited to a magazine...my choice would be the Weekly Standard. :)

CAPTION:
National average SAT scores are compared among states by bar graphs that show deviation of each state from the average. Positive bars indicate state performance surpassing the average while negative bars indicate poorer performance. State participation rates (green shading) are lower in the mid-west where ACT exams predominate.

Week 11: Google Earth

The state of Ohio can boast its efforts to harness alternative energy sources, wind energy being a significant subset of these alternative technologies. The literature that I read through suggests that there are two optimum locations to set up windmill fields, Lake Erie off-shore sites and the northwest regions of the state. These are areas where wind velocities are sufficiently high to make energy production viable. Also, they are areas that would least impact Ohioans from turbine noise, ice shedding, and light flicker. I have identified an off-short location that is with the state jurisdiction of Ohio, is not going to affect shipping lanes, and will not be too close to shore where marshland duck hunting is very popular along with other recreational activities.



I found a map generator for Lake Erie in Ohio at http://www.dnr.state.oh.us/website/OCM_GIS/MapViewer_app/OCM_MainMap/dbGroupToc/myfiles/nsc_metadata.htm. If you link to the entire address, the website will bring you to tables of metadata that are not directly useful. However, by trimming down the web linke, a map viewer locator function opens (http://www.dnr.state.oh.us/website/OCM_GIS/MapViewer_app/OCM_MainMap). I activated layers related to shipping, navigation, and recreation and export the resulting map.



The wind velocities across Lake Erie are greatest on the south side of the lake (within the county boundaries of Ohio). So I found a bathymetric map of Lake Erie at http://www.ngdc.noaa.gov/mgg/greatlakes/lakeerie_cdrom/html/e_gmorph.htm. The location that I propose for the windmill field is off-shore, within the boundary limit of Cuyahoga County, OH (county of Cleveland, OH), and affords optimal wind velocities. The bathymetric map of the area suggests that the basin floor is between 20 and 25 meters below the water surface. This is certainly shallow enough for pilings to be driven down into the geologic base of the Niagara Escarpment to effectively anchor the windmills without incident. The windmill fields would not impact apparent shipping channels and the population would not be affected by ice shedding, noise, or light flicker. The only concern might be for the safety of migratory birds (duck and geese species), however, this is an issue that must be considered for all such operations.

Week 10: Isarithmic Maps

Attached is an isarithmic map of the mean annual precipitation in Georgia. The contour lines were based at 5" rainfall levels. I saw Brandon Isenhart's map while I was working on mine and I liked his legend...I thought it was effective...and resisting the temptation to imitate, I made a more traditional legend where there was not gap between the color symbols.

Week 9: Flow Maps (my better attempt)

Hi Trisha...please note that this is not intended to be my bonus exercise...I wanted to have a history of my own decisions about "good" maps and bad maps. Please use this post for scoring my Week 9 assignment...thanks! :)

Well, I finished my first map and posted it, and then I wanted to go back and make it better ... so I used this lab as an opportunity to delve into greater details with AI. I still find some of the program to be cryptic ... my only real gripe is that I cannot figure out why sometimes the zoom tool permits a "zoom out" option and other times a different dropdown window is activated that does not have the zoom in/zoom out function. ...I am on a mission to figure out the key strokes that toggle between these two dropdown windows ... because it is REALLY difficult to zoom back to the full extent if you can't activate the darn zoom out tool! :) On a more serious note, I think I have created a better flow map in the second go-around.

Week 9: Flow Maps

The attached map shows the relative influx of permananent legal U.S. citizens originating from the various regions of the world. The map-type is referred to as a flow map where the width of each flow-arrow is proportional to the relative numbers of individuals successfully moving from one place to another. I created a literally accurate legend based on the data from which the arrows were made because there were a manageable number of values (9) to put in the legend without the legend becoming too cumbersome. I learned much more about AI although I find many of the tools to be cryptic and hidden in less-than-helpful places. The program also seems to be inconsistent in many ways...for example, with the zoom tool, one time you can right click and access the "zoom out" function, but then, with what seem to be the same key strokes, there is a completely different drop-down menu and no clear way to "zoom out". Most good software packages have more than one way to do the same function...AI seems to be lacking in this flexibility and so you would truly have to become "expert" with its use before you could feel a reasonable level of comepetence with the software as a whole (still expecting good things though!).

Week 8: Dot Map Assignment

This is a dot distribution map of the available housing units in Florida counties. The source of this information was the US Census 2000 data from Census Table GCT-PH1, Population, Housing Units, Area and Density: 2000. Although I had calculated the Housing Density and Population Density from this data set, I determined that it would be most appropriate to use the raw data for housing unit numbers and to place the dots in inhabitable areas (as directed by the course materials). By using the raw data and proper placement of the dots, the "housing density" is summarized by the resulting density of dots in the inhabitable regions of each county. Other presentations of the data might want to use the inhabitablt area of a county when calculating the housing density or the population density. This assignment introduced me to yet another type of map that has significant application value for certain types of data presentation. :) ...I liked it! OOPS, just realized I forgot to put my name and data on it...will update later.

Week 6: Chloropleth Maps (part 3 - update)

Well, I realized that I didn't understand the instructions the first time around, so I decided that I should go back and try complete this assignment the right way! :) Working in ArcMap, I created new layers for each division and I changed the base colors to match a chloropleth legend scale. However, there was a layer detail that I couldn't identify that kept making the New England Division a darker gray than I intended...so I selected each New England state in Adobe Illustrator and changed the gray to a lighter tone. I'm not happy with the scaling on Alaska and would do a few other things to improve this map aesthetically, but I will focus on these functions in future assignments. Argh...that was a matter of back-tracking to catch up from two weeks of being inundated with my other work. ...back on track now !!! :)

Week 7: Proportional Symbol Mapping

The map presented here conveys the 2005 European Wine Consumption rates (www.wineinstitute.org) in units of thousands of gallons per year. This is produced as a proportional map and the detail cartographic work work created in Adobe Illustrator. I grouped the countries by what I believe to be five natural breaks. This caused there to be two countries in the highest consumption category with the value in the legend corresponding to the highest consumption rate. Each legend value corresponds to the highest consumption rate for each break. The Vatican City is the "les than 60" symbol that rests in the larger circle for Italy.

Week 6: Chloropleth Maps (part 2)


Attached is a grayscale map of the 1990 to 2000 population change data by U.S. state. This map is prepared using Equal Value classification. Using Excel, I grouped and calculated division-specific population changes in this time interval.

Percent Population Change by Division

Northeast Region
New England Division: 5.42%
Middle Atlantic Division: 5.50%
Midwest Region
East North Central Division: 7.49%
West North Central Division: 8.94%
South Region
South Atlantic Division: 18.83%
East South Central Division: 12.77%
West South Central Division: 17.76%
West Region
Mountain Division: 33.04%
Pacific Division: 15.07%

Week 6: Chloropleth Maps (part 1)

Here is my first map for the Week 6: Chloropleth Mapping skills lab. I am submitting this now to try to meet the deadline...argh. ...more to come... :)
Learning lots! ...and lovin' it! :)

Week 5: Hispanic Population in South Florida


This map was produced using Adobe Illustrator. It began with several map elements that were arranged and modified and then exported as a png file. The neatline was actually produced in Fireworks. Once I had completed my proposed map layout, I was having alot of trouble moving some of the elements into position. After getting everything into its current position, the neatline was still problematic. So, I opened the png file in Fireworks, a software of which I am more proficient. I chose the blue legend color scheme. The expansion lines were used to show connectivity from the USA Map to the Florida Counties map. To create a visual progression to the primary map, I changed the colors on the Florida Counties map to map the scheme that I was using for the Hispanic Population map. I lined up the left edges of the USA Map box, the legend, and the "Produced By/Source Credit" box to create a sharp-edge "feel" along the left margin. It took alot of thought for me to come up with the layout progression the three maps...I did not want to put each one in a box because I thought it would be distracting. The legend and the Hispanic Population map are lined up to present them as a logical "pair" and the others are lined up to hopefully offer a logical flow from the large extent (USA) to the magnified map of the south Florida counties. Probably the main change that I would make to the map at this point is to lower the two inset maps and create more spread between the top of the neatline and the top of the USA Map box line. I am better with Adobe Illustrator than I was at the begining of the day, ...but there is ALOT more to learn! :)

Week 4: Map Lettering


This map presentation began with a base map that outlined the land masses that combine to form the zone of the Florida Keys referred to as Marathon. The area includes a series of smaller keys along with the primary island key of Marathon. The primary objective of this assignment was to become familiar with the fundamentals of the Adobe Illustrator softward package. Clearly, the software is a powerful resource. Currently, I feel rather "fumbly" and "stiff" with the use of the functions offered by this softward, but I anticipate that time will permit me to work out the kinks. Go UCONN Women's Basketball! ...no better team out there! :)

Week 3: Data Classification

The first map is a comparison of four data classification methods (Equal Interval, Standard Deviation, Quantile, and Natural Break). The objective is to discern the optimum data classification method for the map reader to best understand the relationship being described (i.e. black population) and to clarify distinctions in the census data among census blocks in Escambia County. NOTE: One of the revelations that came to me from this exercise is that the cartographer may inadvertantly or intentionally direct the observer toward an interpretation of the data based on the choice of data classification. Because the typical observer will look first at the general appearance of attributes on the figure (and then, subsequently, at the details...i.e. legend details, data classification-type, etc.)...it is critically important that a cartographer practice with the highest level of integrity and character so as not to falsely direct the interpretation of data through one's map.



I have chosen the Quantile Classification to be the optimum choice for map selection that presents these data. Based on resolution of the legends (all legends held constant at "4" categories), the Quantile Data Classification gives the broadest spread of categories throughout the map while the other data classification methods each produce a monotone spread throughout Escambia County with the exception of the urban area (Pensacola). As long as an informative legend is provide that categorizes the population ranges, the Quantile method permits the broadest zone distinctions and enhances the interpretive value of the map.

Week 1 Assignment: Map Critique Lab

Good Map: I like this map. I understand that it is a more traditional map, but I don't think that a good map has to look "flashy" or "edgy". The label features are clear and read-able. The different point sizes on the label features denote "something" (i.e. province vs city in this case, or "relative sizes" of cities/communities). The color combinations are attractive and aesthetically balanced, however, I do recognize that these are not particularly exciting as colors choices are concerned, the color combinations are appropriate for this type of map.
The legend is embedded on the map...I think that is critically important.

Bad Map: Of the poorly designed maps that I have discovered, this is the one that I want to present. Sadly, this is a map on a Georgia tourism site. I find the proportions to be odd (i.e. the highway symbols are odd-looking and the color contrast hurts my eyes). I do not care for the thin yellow border for the state and the numerical markers are completely meaningless without a connected legend (i.e. it is important for the legend to be more prominently links to the image map).
