Goals Create an online system for geospatial- ecological science End-users: researchers, resource managers, teachers, and the public End-Users can add spatial data –Vector data (text and Shapefiles) –Raster data

Points, Polylines, Polygons

Vector Data A few very large, complex shapes –National parks –Countries –States Lots of small, simple shapes –Individual surveys –Observation points Some regions have very high densities of spatial coordinates

P – Projection time per coordinate L – Loading time per coordinate R – Rendering time per coordinate N – Number of coordinates

Approaches Access only data within viewing area 4 – Maintain All Required Projections –Geographic –3 UTM Zones –All are WGS84 Optimal use of an indexed, relational, enterprise-level database

MZ – Maximum point density

Topology

Rendering from Grid Cells

Equation 7: low resolution –NC – Number of cells Equation 8: high resolution –MH – Maximum point density at high resolution Q1 = maximum time to access indexed data in the database Maximum Rendering Times

Limiting Data Quantity

Field Data Collection The Past The Future + Manual entry+ Automatic upload
