MapWindow GIS ActiveX Control

The core MapWindow
component is a
programming object
(think “MapObjects”)
that can be added to a
form in Visual Basic or
other languages
supporting ActiveX

MapWindow GIS Desktop GUI

A Programmable
GIS that supports:
• Visualization
• Data analysis
• Modeling
• Custom GIS
application
development
• Accepts Scripts
and Plug-ins
• Based on
VB.NET and C#

Models in BASINS




PLOAD – export coefficient based lumped model
•
•
Steady state, spatial, fit, deterministic.
“Screening level” model to look for spatial trends in water
quality based on land cover type
SWAT – soil and water assessment tool
•
•
Dynamic, spatio-temporal, process, deterministic.
Agriculture-centered watershed model
HSPF – hydrologic simulation program FORTRAN
•
•
Dynamic, spatio-temporal, process, deterministic.
Primarily hydrologic process model with water quality
components.
Others…

Simple Models in BASINS
PLOAD Export Coef. Model
LP = U(LPU * AU)
Where:
LP = Pollutant load, lbs/year;
LPU = Pollutant loading rate for land
use type u, lbs/acre/year; and
AU = Area of land use type u, acres
