Tools & Databases

Planning, implementing, and using an effective monitoring program takes the interaction of many different tools and databases.

Sample Design

Shiny Spatially Balanced Sampling Tool

The Shiny spatially balanced sampling tool is intended to let users draw spatially balanced random sampling points within an area based on an ArcGIS polygon shapefile. If the shapefile includes multiple polygons and an attribute table field for stratification, the tool can take that into account to draw sample points by stratum as well.

Data Collection & Storage

Database for Inventory, Monitoring, and Assessment (DIMA)

The Database for Inventory, Monitoring and Assessment is a highly customizable software tool for data collection, management, and interpretation. It is a free Microsoft Access database that can easily be used without extensive knowledge of Access.

Data Analysis & Reporting

Sampling Sufficiency Calculator

The sampling sufficiency calculator is a tool for analyzing a dataset from a user’s DIMA to help determine if there are enough data to meet sampling sufficiency for the level of variability in the dataset.

Simple Horwitz-Thompson Indicator Estimator

The simple Horwitz-Thompson indicator estimator is a tool for producing quick estimates of indicators either by an entire study area or by stratum within a study area from a CSV file exported from a user’s DIMA.

Remote Sensing Image Processing & Analysis

SamplePoint

Developed by Berryman Consulting with the USDA Agricultural research Service and the Bureau of Land Management, SamplePoint is free software for manual image analysis and has built-in functionality for systematic and random pixel sampling, user-defined identification classes, and automatic saving of data.
