Introduction
Agmodel Project provides tools for speeding the development of portable agriculture models. By portable, we mean that models can be easily run in any country rather than being tied to a particular database. Our approach is to create "intelligent hubs" that handle particular kinds of data in a consistent way. Agricultural software applications can access these hubs using distributed computing approaches. Most of the software on these pages is open source - we encourage you to use these tools, and contribute criticism, additions and improvements.
MetBroker
Surface weather records are important for many agricultural models, but weather data is scattered over many different databases and is constantly being updated.
MetBroker provides consistent, timely access to Internet-based weather databases in eight countries.
MetBrokerLite
MetBrokerLite is a lightweight implementation of MetBroker that holds all station metadata in memory. It is suitable for situations where a limited number of small databases need to be linked to a broker. Like MetZoneBroker it retains full compatibility with MetBroker applications, database drivers, and configuration files.
DemBroker
Elevation data (the height of land above sea level) is useful for interpolating weather elements and in hydrological applications.
DEMBroker provides consistent access to digital elevation models (DEMs) with differing formats. Currently DEMBroker provides global coverage at 1km through the GTOPO30 DEM and coverage of Japan at 50m.
ResourceServer
Internationalizing software greatly widens its potential user-base. However, the process of localizing software to each language is time-consuming.
ResourceServer is a Web-based system for handling program text such as button labels and menu items. It lets a software application quickly download the text items it requires in the national language of the user. Translators can add and update the text provided through a Web-based editor.
ChizuBroker
Many agricultural applications require "background maps" to provide a spatial reference frame for users.
ChizuBroker provides applications with consistent dynamic access to rasterized maps from various online sources. Currently maps are available for Japan, New Zealand, US and Europe.

Provides an interactive 3D visualization of terrain anywhere in the world using the VisAD data visualization classes. You need to install Java 3D in order to view this application. You can download Java 3D from here. (Select one of the JRE versions. For Windows the Open GL version seems more stable). | Norway | C |
Applet links above should install the Java Plug-in if required. Click here to download the Plug-In from Sun if it doesn't load automatically.
