Planimetric Coverage containing the delineation of topographic contours at two foot intervals.

They are located in flat areas where contours may be sparse or spaced far apart, at road and railroad intersections, on the road centerline at the ends of bridges, on the road centerline over the center of culverts that have a span of five (5)-foot or greater, at the crest of all tops of hills, at saddles, within depressions and where the ground is visible in obscured areas. Spot Elevations are used to show additional elevation information. They were created from a DTM Feature Dataset, upgraded by Baker and T-3 to support National Mapping Accuracy Standards (NMAS). Spot Elevation data was created as a result of a county flyover in the spring of 2004. Metadata | Download | Preview | Add to ArcMap: Image or Feature | Add to ArcGIS Pro | More Options. Contours are coded separately for delineation between depression and intermediate contours. Depression Contours are contours showing the edges and slope in a depression at 5 foot intervals. Intermediate Contours are contours spaced at 5 foot intervals. Contours were created from a DTM Feature Dataset, upgraded by Baker and T-3 to support National Mapping Accuracy Standards (NMAS) for contours.

Online programs (ArcGIS Online) are available by visiting Lehigh’s enterprise site and logging in with your credentials. LUapps can be accessed both on campus and off-campus (over VPN). For ArcGIS desktop programs, users can either download and install the software directly onto their machine, or they can access the programs through LUapps, a virtualized software system. ![]() These tools, collectively known as ArcGIS, include desktop and online programs, and mobile applications. Here at Lehigh, students, faculty, and staff, have access to a suite of tools designed by Esri to build and work with GIS data. Today, GIS is used in almost every field to aid decision making by visualizing and exploring data patterns, trends, and relationships. ![]() Early work in the field of GIS started in the 1960s to manage natural resources. Rooted in geography, GIS integrates spatial location with layers of information. A geographic information system (GIS) is a framework for gathering, managing, and analyzing data about the world around us. ![]()
