Making A Geologic Map With Arcgis
ArcCatalog is a general-purpose data management utility that comes as a part of the ESRI ArcGIS package. Most of our setup steps for parts one and two will be conducted in this program prior to working with the LiDAR data in ArcGIS. Start ArcCatalog by clicking on its icon (a yellow file cabinet) under the ArcGIS subfolder of the Start menu.
A Workspace is a location on the file system where you keep all of your map data for a project. This location must be named so that it obeys the rules of names, above. For example, the common default working directory for ArcGIS is C: workspace.
This section is for preparing a field map for digitizing in ArcGIS. If you are mapping directly from satellite imagery you can skip to the next part of the tutorial.
ArcMap works under two different 'views' - data view and layout view. Until now you have been using the data view. Change to layout view under the view menu. You will see a page with your map in the center drawn at some arbitrary scale that fits on the page. Make the map a fixed scale of (e.g. 1:20,000) under the view->data frame properties- >data frame dialog box.
