ProjectsA collection of projects I have

completed that are cartographicallycorrect and showcase the skills I

have learned in ArcGis

The purpose of this map is to help a newhomebuyer assess the locations of 4 possible

homes represented by 4 colored stars. They wereinterested in possible geologic hazards such asfaults and liquefaction along with the proximityof hospitals, schools, fire stations, and LDS

temples.

New Skills Learned and Applied:

-Correctly set up a new map in ArcMap with the default geodatabase correctly defined.

-Imported all data into a newly created geodatabase

-Converted excel spreadsheets with x,y coordinates intofeature classes and added them to the geodatabase

-Added a hillshade with an adjusted z factor for bettervisualization.

-Used the ‘dissolve’ tool to dissolve the soil and bedrock

-Created inset and locator maps with ‘extent indicators’

-Created Legends

-Inserted scales and a north arrow

-Added labels to better understand the data

-Converted a kml file of LDS Temples and added them to the ArcMap.

-Used the ‘clip’ tool to clip both vector and raster data

-Added labels and changed symbology to make the map look more professional.

-Cartographically correct with sources and other info in the bottom right hand corner.

New Skills Learned and Applied

-Georeferenced an image of a geologic map

-Created a feature dataset

-Added topology rules to my dataset

-Used the ‘editor’ toolbar to digitize a geologic map.

-Used my knowledge of geologic maps to correctly label faults and contacts when digitizing

-Used the ‘topology’ toolbar to correctly fix the errors.

-Inserted strike and dip locations and allowed the symbol to rotate according to the azimuth

-Included the style reference ‘geology 24K’ so that I could properly label geologic units and features.

-Converted the labels to ‘Annotation’ so that I could move them to a better location.

-Added a basemap

New skills learned and applied:

-Used ‘slope’ to find the steepness of the slopes.

-Used ‘raster math’ to find the difference between the before and after Digital Elevation Models of Mt. St. Helen.

-Used ‘contour’ to create contour lines.

-Created topographic profiles using the 3D analyst toolbar.

-Used ‘viewshed’ to see the visible areas from the observation point

-Added legends and text to better understand the details of the poster

-Imported photographs

New Skills Learned and applied:

-I found my own data on the web from multiple sources.

-Used the ‘local polynomial interpolation’ to create contours from point data.

-Reclassifed all of my maps in order to make a suitability study.

-Used ArcScene to better visualize what is occurring in thecanyon.

-Adjusted my base heights and offsets to be able to see allof the data.

-Organized it with text boxes and neatlines

Other MapsMultiple maps that show other

skills that I have gained in usingArcGis


- I used the 'define projection' tool to properly define the data that had unknown coordinate systems to NAD1927 UTM 12N

- I used the 'project' tool to properly project the data that was found in Clarke 1866 to NAD1927 UTM 12N.

- After projecting my data all to the same projection in ArcCatalog I then transferred the data to ArcMap.

-Used ‘Select by Attribute’ to find only the fires thatwere caused by lightning strike

-Adjusted the symbology and classified the 5 scales of elevation so that they were more uniform.

- Added a graticule to my locator map.

Improvement:

I would make the legend more clear showing that the reddots are locations in which fires have started due to lightning strikes. Some people might be confused thinking that the red points are all the places in which lightning have struck.


-Georeferenced an aerial photograph

-Used a transformation that allowed the least amount of RMS Error.

-Converted an excel table with xy coordinates into a feature class.

-Used the ‘editor’ toolbar to trace and highlight the flooded region.

-Used the ‘snapping’ toolbar to edit lines more accurately and effectively

Improvement:

I would add a locator map to better understand where this area islocated.


-Used ‘select by location’ to properly select springs and wells within a certain region

-Created a choropleth map of the populations in each county within the state of Idaho.

-Created buffers of certain distances around a particular point.

-Used the ‘intersect’ tool to create a new feature class of an area that lies within two separate polygons.

Improvement:

To make this map better I think I would change the colors around.The Area of Interest and Ada County boundaries are a little hard to tell apart from the rest of the background. I would also organize it differently.


-Downloaded two separate DEMs from the USGS website.

-Exported them into ArcCatalog

-Used the ‘Mosaic’ tool to combine them so they are one DEM.


-Used ‘slope’ to find the steepness of the slopes

-Used ‘aspect’ to find the direction that each slope faces

-Used ‘viewshed’ to find the visible area from a specific point

-Used ‘contour’ to create contour lines of the DEM

-Adjusted the azimuth and altitude of the hillshade in order to make them more visible

Improvement:

To make this map better I would add a scale bar and north arrow. It also seems a bit cluttered so I would try to make my data frames smaller so I could have more space and more organization.


-Adjusted the symbology of the slope by changing the standard deviation to 5 (this creates a better visual of what the area actually looks like).

-Used ‘curvature’ to better visualize the drainage basin in a specific area and to observe the erosion and runoff processes.

-Created contours for the raster data of the slope in order to better visualize the rate of movement downslope.

Improvement:

To improve this map I would choose different colors to try and make the slopes and curvature more visible. I would also add legends for the upper maps to fill some of the empty space on theright side.


-Used the ‘reclassify’ tool to change the values of certain attributes.

-Used ‘reclass by table’ in order to reclassify the land cover data

Improvement:

To make this map look more cartographically correct I would add north arrows and scale bars for each map.


-Used the ‘weighted overlay’ tool to place all of my reclassified maps into one suitability study

-Changed the % influence of each data frame to find themost suitable locations

Improvement:

To improve this map I would change the legend to make it more specific so the audience could understand what the numbers 1-6 meant. I would add my data sources in the bottom right hand corner.


-Used model builder to create a full drainage analysis

-used ‘flow direction’ to understand what direction thewater will flow

-Used ‘drainage basins’ to see the drainage basins in the area

-Used ‘stream order’ to find the order of streams usingthe Strahler method

-Used ‘flow accumulation’ to find how much water was flowing in each stream

-Used ‘con’ tool to select the values of streams that Iwanted to see

Improvement:

To improve this map I would add scale bars and north arrows to each map.

New Skills Learned and applied:

-Used the ‘Geostatistical Analyst’ tool bar to analyze point data

-Used Global Polynomial Interpolation, Local PolynomialInterpolation, and Kriging

-Used Trend analysis to visualize the data

Improvement: I would add a basemap to see where exactlythis data is located. I would also add legends, north arrows, and scale bars.
