| 1: | Automated generalisation of polygonal data in thematic mapping EGIS (1994), copyright EGIS Foundation. AUTOMATED GENERALISATION OF POLYGONAL DATA IN THEMATIC MAPPING Katherine Mak European Product Coordinator, Map Scanning & Cartography Intergraph European Headquarters Hoofddorp, The Netherlands ABSTRACT The demand on thematic mapping has recently increased as government agencies are required to provide comprehensive and accurate ecologically based inventories of natural resources. As such, there is a growing desire for inventory programs to produce multiple scale thematic representations. To meet this type of need, capabilities for area cover (typical of thematic maps) generalization is required. Most research on automated generalization has focused on linear features in topographic mapping. Area information is best represented, in digital cartography and GIS, as polygons. The requirements for generalizing polygonal data in a digital environment are more demanding. This is especially true in thematic mapping whereby spatial adjacency ... http://spatialodyssey.ursus.maine.edu/... b/egis/eg94185.html |

| 2: | Okefenokee Swamp vegetation mapping with LANDSAT thematic mapper data: an evaluation ASPRS/ACSM (1994), copyright ASPRS/ACSM OKEFENOKEE SWAMP VEGETATION MAPPING WITH LANDSAT THEMATIC MAPPER DATA: AN EVALUATION C. P. Lo Department of Geography University of Georgia Athens, GA 30602-2502 Lee J. Watson Department of Geography and Regional Planning Salisbury State University Salisbury, Maryland 21801-6837 ABSTRACT The capability of Landsat TM data in mapping the vegetation communities of the Okefenokee Swamp was evaluated using a GIS approach. Because of the nature of the Okefenokee Swamp as a mosaic of dynamically related vegetation patches representing different stages of temporal succession, the spatial resolution of the TM data was found to be inadequate to produce a 21-class vegetation map compatible in accuracy to that of the reference map produced from large-scale color infra-red aerial photographs and field work. By aggregating the 21 classes of wetland vegetation into 6 classes of gross vegetation types, the accuracy of the map was greatly improved. ... http://spatialodyssey.ursus.maine.edu/... b/acsm/ac94041.html |

| 3: | The Kansas State Land Cover Mapping Project: regional scale land use/land cover mapping using Landsat thematic mapper data THE KANSAS STATE LAND COVER MAPPING PROJECT: REGIONAL SCALE LAND USE/LAND COVER MAPPING USING LANDSAT THEMATIC MAPPER DATA Jerry L. Whistler, Stephen L. Egbert, Mark E. Jakubauskas+, Edward A. Martinko, David W. Baumgartner, and Re-Yang Lee Kansas Applied Remote Sensing (KARS) Program 2291 Irving Hill Road University of Kansas Lawrence, Kansas 66025-2969 ABSTRACT The Kansas Applied Remote Sensing (KARS) Program recently completed a three-year project to develop a map of land use/land cover for the State of Kansas. During the development phase of the Kansas State Geographic Information Systems Initiative, numerous state and federal agencies indicated that land use and land cover were critical to their management and planning missions. After considering several options, computer classification of Landsat Thematic Mapper (TM) data was selected as the most cost-effective and timely approach. Five urban land cover classes were mapped: residential, commercial/industrial, open ... http://spatialodyssey.ursus.maine.edu/... acsm95/ac95149.html |

| 5: | Automated mapping and GIS in Florida local planning agencies mail survey gathered general information about the use of computers for planning purposes in Florida's 392 cities and 67 counties. Among local governments with planning agencies that use computers in their daily work (196), roughly half of them are using automated mapping or GIS technology for planning. This indicates a fairly high acceptance level of this technology (21% of all cities and counties in Florida). A more detailed survey looked at 96 local governments which said they use GIS, CAD, or thematic mapping software in their planning agency. The response rate for the second survey was 100%. The paper summarizes several key findings from the surveys, including: how automated mapping systems and GIS are used in local planning agencies hardware and software trends similarities and differences among cities and counties using this technology the amount of personnel and money invested in these systems organizational problems agencies have experienced with these systems ... http://spatialodyssey.ursus.maine.edu/... /urisa/ur94068.html |

It introduces the elements of graphic design, particularly as applied to thematic mapping. The survey includes general (topographic) and thematic mapping; two and three dimensional representation; the geometric and the aspatial (attribute) information portrayed with maps. It also uses computer technology to demonstrate the topics discussed. The techniques of computer programming behind digital cartography provide a new method to handle the structure of cartographic information and are worth study on their own.

| 10: | Pittsburgh analytic atlas project detailed development and documentation of tools necessary to implement the Analytic Atlas. The background for a computer based census atlas, the conceptual basis for what constitutes an Analytic Atlas, implementation details, and an evaluation of cooperative arrangement constitute the subject of this paper. HISTORIC EXAMPLES OF COMPUTER URBAN CENSUS ATLASES: In this age of desktop mapping and geographic information systems the production of maps showing census information is commonplace. Quick thematic mapping is even being added to common spreadsheet programs. The apparent ease of mapping belies the long development paths for quality mapping of census information. Space does not permit here a full examination of those developments or appropriate mention of quality census maps generated by many cities across the country. Rather two notable efforts deserve mention because of their use of computer technology in their respective eras and as benchmarks to compare and contrast ... http://spatialodyssey.ursus.maine.edu/... /urisa/ur94080.html |
