Herodotus GIS Author

Author supports the following industry-standard GIS formats:

• GIF, JPEG, PNG, TIFF (read and write)
• SHP, MIF, SED (read)
• UK Ordnance Survey NTF (read)
• Open GIS Consortium Simple Features
• PDF (export)

In addition, Author supports the following proprietary GIS formats:

• Herodotus GIS Archive (HGA): Simple ASCII format for archiving vector data
• Herodotus GIS Dataset (HGD): Editable vector data, with attributes, styles and spatial index
• Herodotus GIS Pyramid (HGP): Multi-resolution image data
• Herodotus GIS Raster (HGR): Highly compressed raster data (e.g. Digital Elevation Models)
• Index Dataset: Coverage of rectangular tiles in various formats

Author includes a wide range of GIS functionality, including:

• View maps (pan, zoom, projections etc)
• Continuous mapping (index datasets)
• Overlay raster and vector data
• Themes, annotations and filters
• Print layouts
• 3D viewing
• Network analysis
• Edit geometry
• Edit attribute data
• Clean map geometry (e.g. fix up overshoots and undershoots)
• Triangulation and Voronoi/Thiessen coverages
• Measurement (meters, feet etc)

Herodotus GIS Developer

• Herodotus GIS Author
• Herodotus GIS Server Beans
• Herodotus GIS DeskTop Beans
• Herodotus GIS Components
• Herodotus Mobile GIS
• Source code for sample custom applications

With Herodotus GIS Developer you can use the runtime products for testing, but their performance is deliberately limited in various ways so they are unsuitable for deploying your application. When you deploy your application, your customers should buy their own Herodotus GIS runtime products, so that they can run your application with full performance.

Herodotus GIS Server Beans

The beans are designed to work efficiently in multi-CPU servers, by making use of fine-grain thread synchronization, and the advanced memory management features of the Java language (e.g. soft references for caching data).

Using Herodotus GIS Server Beans, you can develop your own GIS server applications (servlets). Typically, your servlet would run inside a Tomcat server. It would receive HTTP requests from clients, and then use Herodotus GIS Server Beans to render GIS images in GIF or PNG format. Alternatively, your servlet could prepare data for the clients in PDF or Animated GIF format.

You will often use Author to prepare large volumes of GIS data in formats that are optimized for your servlets. That way, your servlet will run efficiently, and will be able to support lots of clients simultaneously.

Herodotus GIS DeskTop Beans

In fact, Author itself is based on these beans, so by using Desktop Beans you can develop your own advanced GIS applications.

With Desktop Beans you can do the following:

• Customize Author by adding your own menu commands
• Write your own GIS User Interface, using Java Swing
• Write your own GIS applications and utilities

Herodotus GIS Desktop Beans is optimized for single-CPU machines.

Herodotus GIS Components

Using Herodotus GIS Components, you can develop your own GIS applications in Microsoft Visual Basic, Visual C++ or C#.

Herodotus Mobile GIS

Currently, mobile devices are significantly less powerful than desktop computers, and GIS applications are often CPU intensive. Recognizing this, Herodotus Mobile GIS was specially designed for use on less powerful devices. For example, to render maps quickly it uses special algorithms that rely on Herodotus's proprietary HGD file format.
