Conventions for File Management

We adopted some simple conventions to manage the complexity of file management for our project. While our conventions remained fairly consistant, the names of some data layers did change between both study areas. All the data uses datum NAD 1983 and uses projection HARN State Plane Colorado South FIPS 0503. The data files for each study area are kept in separate directories within a directory for the projected data. This is shown below:

For each study area, the required files are described below.
