Week14-Final Project

     This study was made to determine what impact the BobWhite-Manatee transmission project would have the on environmentally sensitive lands, Homes along the proposed corridor, Parcels inside and abutting the transmission line and schools and daycares.
     After completing our study it was determined that in the overall corridor minimal environmentally sensitive lands were impacted, 78 homes, 132 out of 10,886 parcels in Manatee county and 30 out of 1,474 parcels in Sarasota County were impacted and no schools or daycares were affected.
     The total impact on both counties were minimal considering the transmission line extends 25 miles.

Lab 13 Georeferencing, Editing & ArcScene

     In this chapter we learned how to georeference data, interpret root mean square errors, digitize new building and road features and practice polynomial transformations. We also we able to create hyperlinks, multiple ring buffers, customize an Arcmap toolbar and overlay data in a 3D environment.
     The above map shows the rasters we used to georeference, the building and road we edited and created a new polygon feature for and the buffer area we created using the multi ring buffer tool. The map below shows how we created a 3D rending of the UWF Campus using ArcScene

Lab 12 Geocoding

     In this weeks lab we were introduced to Geo-coding, Network analysis extension and model building. We had to create an address locator, conduct Geo-coding by address matching, resolve common issues that arise such as addresses we cannot match up in ArcGIS and complete a route analysis using network analysis extension.
     Finally we were able to develop a map that showed us where EMS stations in Lake County Florida were located and analyze a route choosing three specific locations.

Lab 10 Vector Analysis 2


     In this chapter on spatial analysis of vector and raster data we have been asked to use buffer and overlay, two of the most common modeling tools in ArcGis to analysis spatial data, use both Arctool box and Arcpy to buffer and overlay feature classes and to combine or exclude multiple features to distinguish multi-part and single part layers. 
     In the end we were able to perform various buffering analysis functions, use Arcpy to complete single and multiple buffers at once and overlay feature classes in order to single out desired campsites with 300 meters of a road and either within 150 meters of a lake or 500 meters of a river as well as exclude conservation areas from the site selection.

Week 7 Data Search Lab



     In this weeks lab we are utilizing all that we have learned to this point in order to develop a multi layered map using nine different layers. We used multiple data sources to learn how to research data, download and prepare spatial data and project it in ArcMap. 
     We were able to use multiple data frames, bring in multiple layers and through defining projections we were to make a readable and cohesive map.

Week 6 Lab on Projections Part 2

     In this weeks lab we were asked to down load aerial maps, topographic quadrangles and shapefiles from the labins.org site and the Florida Geographic Data Library Metadata Explorer (FGDL.org). We were able to find this spatial data, define the spatial reference found for this data and apply a single projection system. We were also able to calculate coordinates through the use of excel and merge this data into our map.
     Finally we had to complete a project from a quad of our own choice using data from these sources which included and aerial image, Florida County boundaries, Major Roads, a shape file from STCM data and our selected quad and develop a map that has a common coordinate system, had an imported table that was accurate and where the different layers were in line with each other.

Week 5 Projections


     
In this weeks lab we were asked to provide a map showing three different projection systems and a table showing the areas of four different counties in Florida. We were then asked to compare the data in the table and determine what the differences were when using each projection system.
     The Albers system is used usually to depict the United States and used for world mapping  and is popular is because it is an equivalent projection, it is simple to construct and is easy to segment and reassemble although it does contain small errors in scale. The State Plane system is not a projection but a coordinate system which is based on two different projections and has 120 numbered sections, used mainly to the divide the states. The UTM system uses 60 zones, both north and south and separated by the equator. Each zone spans 6 degrees of longitude and has its own central meridian. It is used for world mapping and is more precise when mapping a more specific area.
     When comparing the three different projection systems it appears the Albers is great for larger area maps but information would not be as accurate for more specific areas. The State Plane system would be good for information on a statewide basis and the UTM system would be most accurate for counties, cities and town information.
