13 13 www.geongrid.org CYBERINFRASTRUCTURE FOR THE GEOSCIENCES IGEON 2007 at the University of Hyderabad, India, August 02-08 2007 13 Benefits of Web Services Facilitates reuse of existing assets Lower cost of maintenance Reduced impact of change Example –GEONgrid AsciiToMap, XMLToMap, ShapeToMap Benefits include availability of useful functionality on the web –Arcweb Services Pool of web services that provide mechanism to access data and GIS functions on demand. Benefits include, access to terabytes of spatial data, complex GIS functionality, etc.

14 14 www.geongrid.org CYBERINFRASTRUCTURE FOR THE GEOSCIENCES IGEON 2007 at the University of Hyderabad, India, August 02-08 2007 Simple Web Services ASCIIToMap –Have tab delimited file, don’t have expertise/technology to create maps. ShapetoMap –Have the dataset in shape file format, don’t have expertise/technology to create maps. ESRI Grid Ascii to Map (GeoTiff) –Have a GRID ASCII file, want to create map.

15 15 www.geongrid.org CYBERINFRASTRUCTURE FOR THE GEOSCIENCES IGEON 2007 at the University of Hyderabad, India, August 02-08 2007 ASCIIToMap Tab delimited file with spatial information –Example from the SCEC website (lat, lon, magnitude) –Only point dataset supported at this points Upload the ASCII file and create map View and analyze the results ASCII2Map Web Service –takes an ASCII file as Input –creates GIS map as output –creates shape file as output

22 22 www.geongrid.org CYBERINFRASTRUCTURE FOR THE GEOSCIENCES IGEON 2007 at the University of Hyderabad, India, August 02-08 2007 Same Principle as RADAR The lidar instrument transmits light out to a target. The transmitted light interacts with and is changed by the target. Some of this light is reflected / scattered back to the instrument where it is analyzed. The change in the properties of the light enables some property of the target to be determined. Same Principle as RADAR The lidar instrument transmits light out to a target.
