3 OSGIS Software Stacks… Desktop Generic StackFOSS4G StackGrouping ApplicationQGis, Grass, OSSIM, JUMP, UDig User Interface Application Dev. Environment Eclipse, QT, OpenGL, Tkl/Tk High Level Utilities GeoTools, Postgresql, PostGIS Data Serving High Level Scripting Languages PHP, PERL, Python Low Level Utilities Shplib, GEOS, OGR/GDAL, R-Statistics, GMT Data Processing/ Formatting Low Level Languages C, C++, Java, FortranSystem Software Operating System Linux, Darwin, Cygwin Hardware Drivers bit processor drivers Desktop Software Stack

6 OSGIS – Server/Web Tools GRASS GIS GDAL/OGR R-Statistics

7 Desktop Raster/Vector Processing GRASS/GDAL/OGR - Data Crunching Both Raster and Vector support Very powerful tool set (similar to ArcINFO/ArcGRID) Traditionally Poor GUI, but getting better Very fast Cross platform QGIS/GDAL/OGR – Data Viewing/Editing Both Raster and Vector support Nice GUI Cross platform QGIS can integrate with GRASS

8 GRASS-Raster Grass Raster Processing

9 GRASS-Vector Grass Vector Processing

10 QGIS - Titan QGis 0.8

11 Mapserver Web-Based Interface AJAX-User Based Data Filter GMT generated graphics Spatially constrained queries and scenarios Chameleon Mapserver framework PostGIS Spatial Data

12 Slippy Maps…OpenLayers Google Like Tools Tile based image server Super Slippy!

13 Now what…. How is this useful to you???????

14 Personal Use…. Thanks to Dylan Beaudette : Navigating Wilderness Areas with GRASS Classification Cost Surface

15 Creating Data…. Digitizing, Modifying, extracting… Context Layer Viewing Create new shapes Create new attributes

16 Transforming Data…. How to get coordinates in UTM to Geo-NAD83?

17 Web enable standard geo-data….

18 Web enable non-standard geo- data…. How to display and interact with model data? GIS Model Results Web Based Real-Time GIS Model

19 Spatially enable your database…. How to select data within a polygon area? Intersects Geometry Definition Distance(geometry, geometry) Equals(geometry, geometry) Disjoint(geometry, geometry) Intersects(geometry, geometry) Touches(geometry, geometry) Crosses(geometry, geometry) Within(geometry A, geometry B) Overlaps(geometry, geometry) Contains(geometry A, geometry B) Intersects(geometry, geometry) Relate(geometry, geometry, intersectionPatternMatrix) Relate(geometry, geometry) Centroid(geometry) Area(geometry) Length(geometry) PointOnSurface(geometry) Boundary(geometry) Buffer(geometry, double, [integer]) ConvexHull(geometry) Intersection(geometry, geometry) SymDifference(geometry A, geometry B) Difference(geometry A, geometry B) GeomUnion(geometry, geometry) GeomUnion(geometry set) MemGeomUnion(geometry set)

20 Display unique data…. How can I plot geospatial and model data? #!/bin/csh # #GMT Example 24 $Id: job24.csh,v /05/08 01:35:12 # # Purpose:Extract subsets of data based on geospatial criteria # GMT progs:gmtselect, pscoast, psxy, minmax # Unix progs:echo, cat, awk # # Highlight oceanic earthquakes within 3000 km of Hobart and > 1000 km echo "147:13 -42: Hobart" >! point.d cat ! dateline.d > Our proxy for the dateline EOF set R = `minmax -I10 oz_quakes.d` pscoast $R -JM9i -K -Gtan -Sdarkblue -Wthin,white -Dl -A500 -Ba20f10g10WeSn \ -U"Example 24 in Cookbook" >! example_24.ps psxy -R -J -O -K oz_quakes.d -Sc0.05i -Gred >> example_24.ps gmtselect oz_quakes.d -L1000/dateline.d -Nk/s -C3000/point.d -fg -R -Il \ | psxy -R -JM -O -K -Sc0.05i -Ggreen >> example_24.ps awk '{print $1, $2, 0, $3, $3}' point.d | psxy -R -J -O -K -SE -Wfat,white >> example_24.ps awk '{print $1, $2, 14, 0, 1, "LT", $4}' point.d \ | pstext -R -J -O -K -Gwhite -D0.1i/-0.1i >> example_24.ps psxy -R -J -O -K point.d -Wfat,white -Sx0.2i >> example_24.ps psxy -R -J -O -M dateline.d -Wfat,white -A >> example_24.ps \rm -f point.d dateline.d.gmt* The Generic Mapping Tools
