SERVIRMODIS and OSM Acquisition Data Analysis, Processing, Serving
Acquisition • Data Creation • Point, Line, Polygon, Linear Polygon • Feature Class Determination (Shoreline v. Island) • Attribute Fields and Data Types (Google Example • Centralized System • Take the tools and implement into one system • SDP Toolkit,
Acquisition, Serving, Processing MODIS WIST, LPDAAC, NASA catalog ArcServer and Envi – HDF EOS/4/5 Algorithm to GeoTiff HEW Subsetting SDP Toolkit RBDMS – ARCSDE and Raster Catalog Routine for Imagery Extraction HEG - HDF to Geotiff Imagery Extension Reprojection on the fly
Acquisition, Serving, ProcessingOSM • Sources • Planet OSM • Cloud Made • Comparison Datasets • Google Earth, Virtual Earth, Military • National Datasets • Needs • Usable attribution – Geodatabase dropdowns • 2D and 3D datasets • Terrain Dataset (soils, slope) • Regional Collaboration for Roads Surveys Standards
Spatial Data Management Scheme (1) • SDI, ISO 19133 and TransXML (in process) • Current International Standards Analysis • OGC/Model Identification – Short and Long-term Needs • Hierarchical Attribution and Symbology Standard • Spatial Capabilities / Raw Data Functionality • Network and Volume/Flow Analysis • Viewshed and Least cost path analysis • Routing and Statistics • Economic Development/Political • Supporting Infrastructure • Probability Hazards Mapping and Emergency Response • Modal Transfer Points (Planes, Trains, and Automobiles)
Spatial Data Management Scheme (2) • ArcSDE Geodatabase(s) • Translation into the SERVIR schema • XML/GML cooperative • Editing, Validation/Verification • Comparison Matrix • Updating and Resubmission to OSM • Example SANGIS Schema
Issues • Issues • Error (User/Interface/Methodology/Standards) • Missing Data and/or Attributes (Example) • Duplicate Data (Example) • Topology and Geometric Shapes (Example) • Aggregation (Example) • National Level Datasets Projections • International Geocoding Diversity • Languages Utilized and Displayed (Example) • Legends and Data Investigation
Development Environments and Technologies (1) • ArcSDE Geodatabase • Geoprocessing tasks • Out of the box • Toolshare • Model Builder • Scripting/OGC/Javascript API • Open Layer Jquery (pop-ups, document management delivery) • ArcServer Capabilities • Simultaneous Editing and Automated Validation/Verification • Identification of Data in Web Applications v. WMS • Spatial and Statistical Tools and Analysis • Conversions and Exports >>> arcpy.AddField_management("c:/data/Portland.gdb/streets", "LENGTH_MILES", "TEXT") >>> arcpy.CalculateField_management("c:/data/Portland.gdb/streets", "LENGTH_MILES", "!shape.length@miles!",
Performance and Sustainability • Guidelines • If it doesn’t work, no one will use it! • If it is difficult to use or lengthy instructions, no one will use it! • If the functionality is weak, no one will use it! • Design Responsibilities • Maximum use of progressive technology and scripting effectively • Algorithm and Work Flow identification • Parallel Processing • Expandability and Network Links/WMS/WFS • Testing • Capabilities • CONTENT and CONTEXT – “Purpose and Message” • Thin Client • Speed • Individual Investigation – DSS for cross/multiple disciplinary knowledge workers • Data Interoperability
Development Environments and Technologies (2) • ArcServer and Server Technologies • FLEX, Silverlight, and Sharepoint - API libraries and templates • 3D Explorers (ArcExplorer, GeoPDF, NASA Worldwind(Flex), AGI SDK) • Unlimited Extensible Possibilities (GeoPDF, Google Earth and Embedded Maps) • Multiple Import/Export Data Sharing Methods (KML, XML) • API’s (Embedding, Routing, Geocoding) • Open Layers + Query • Issue – Need for keys for user in some cases • User Interface Language Control • Mobile GIS • Web-based digitizing • Internet GIS (ArcServer, Flex, Services) • Google Imports • Geographic PDF Comment and Markup (Adobe Reader) • Smart Phones
Cartography • Demonstration • Symbology • Coverages • WMS Imports and Sharing • Principles • Products • Illustrator Maps • Geographic PDF’s
Data Tables and Data Types • Classification and Symbology – Spatial DSS – Network Analysis and Statistics
Approach • Investigate and Drill Data • Analyze Data Creation Methods and Standards • Current for needed products • In conjunction with Short and Long-term goals • User Needs Analysis and Skill Set Accommodations • Systematic Algorithm (Input to End User) • System Architecture and Interoperability
