In essence, distance decay describes how things like communication and infrastructure break down relative to distance from a cultural center. This leads to cultural differences between an urban ... read more December 18, 2011MetadataData, Learning GIS, Spatial AnalysisWhat is metadata and why is it important to document GIS data? Metadata is an important, but unfortunately oft overlooked component of GIS data. Metadata is ‘data about the data’ and it’s vital to understanding to source, currency, scale, and appropriateness of using GIS data. Metadata can be stored as an inherent part of the ... read more August 31, 2010 Free Network-Based Analysis SeminarSpatial AnalysisEsri’s offering a free ArcGIS seminar to show how to conduct network-based analysis using Spatial Analysis.
