Automation of Map Generalization - Esri Support ArcGIS
The Working Group on Map Generalization under the International Cartographic Association (ICA), as part of the Commission on Advanced Technology, was formed at the fifteenth International Cartographic Conference (ICC) in Bournemouth, United Kingdom, in 1991 It has played an important role in providing a forum for

GIS: Definition
Geographic Information System(s)
A computer system for capturing, storing, checking, integrating, manipulating, analyzing and displaying
data related to positions on the Earth's surfaceTypically, a GIS is used for
handling maps of one kind or another. (from thefreedictionary.com)Map layers
Raster data
: imagesrows and columns of pixelsSAR data, DEMs, scanned maps"continuous" change, spatiallyGeoTIFF, JPEG, binary, etc.
Vector data
: points, lines, & polygonsGPS points, satellite swath outline, lat/long
grid "discrete" changeshapefiles, coveragesEOS Data Gateway (EDG) = GIS

for addressing spatial data challenges •Fairbanks DEM•Tanana C rossing•MatSu DEM•Various user questions•N60 Tandem coverage•IceSAT•Texas corner reflectors
Fairbanks DEM input coverage
ERS orbit swaths
"deeper" input coverage improves resultsFewer input layers, more noise in results
GIS allows multiple layers, in any
combination, to be viewed at onceAIRSAR with GCPs
•13 AIRSAR strips combined as DEM/AMP mosaic of Fairbanks area •Ground control points chosen for distribution, dual use, and accessibility•GIS allows scrutiny of individual raster inputs, potential GCP locations, and "big picture" coverage
DEM & GPS height comparison
•30,000+ GPS points collected by DNR•Diff. Corrected•Compared to DEM height using ArcInfo

User Questions
RAMP data
ESRI coast
•ASF User reported misalignment between the RADARSAT Antarctic Mapping Project data and other GIS layers•ArcGIS allowed comparison of the data with stock vector layers (lat/lon, coastline), reproducing User experience•Error probably lies in polarstereographic projection definition, (latitude of true scale = 90?)
User Questions
•ASF User reported geocoding problem with ASF RADARSAT data, misalignment with vector coastline file•Discussed post-processing of SAR by User; ASF tool versions•SAR data and coastline file (.as
c) sentto ASF•MATLAB coastline converted to ESRI point vectors, then to lines•Observed agreement between SAR data and coastline when compared at ASF
Monterrey Bay
RADARSAT data
Coastline vector layer
User Questions
•Observed agreement between SAR data and coastline when compared at ASF (within SAR g eolocation s pec) •Error probably in User's generation of coastline file from ASCII data (State Plane?)N60 Project: ERS DEM coverage
