J'Dante's GIS Blog

For week 12 of GIS lab and final week before the final project, we took a look and Georeferencing and Lidar. We use georeferencing to make control points and try to match the buildings with the aerial raster photos to get them as accurate as possible. With that we took the location of an eagle's nest and made a multi buffer layer with an given scenario. Also, we created a 3D elevation model with the use of Lidar data which was coverted to a DEM. The skills performed in this lab will be put to use in the final project. Not only will they be used in the final but even down the road as I build on my GIS knowledge. The maps above showase the use of georeferencing and Lidar data.

For week 11 of GIS Lab, we took a look at geocoding and performing a network analysis of Emergency Medical Services(EMS) in Lake County. Specifically, with that network we created a route including 3 different EMSs. Geocoding is a very important part of maps because they require a high level of accuracy to map points. Locations and street names can possibly change, so it is impairative to stay on top of it especially if EMSs are involved. As simple as it looks, it required the use of a MyAddressLocator which was use with a Geocoding Table to match all the locations a provided table. Some of the points had to be manually matched with the rematch process and the use of Google Maps to find the actual locations. The map above showcases the process of Geocoding and a network analysis.
