Giza

The fastest way to stream imagery from the cloud

Giza brings enterprise user permissions, usage analytics, and the responsiveness you need into your imagery program.

What is an imagery service?

A advanced imagery streaming service like Giza makes it possible to stream imagery data (such as maps or aerial imagery) directly from cloud storage for use in web applications or desktop GIS and CADD softwares. An image service typically uses WMS or WTMS (OGC standards for serving map images or tiled imagery data via an HTTP interface). The primary goals of imagery services are high speed and easy access to imagery libraries stored in the cloud.

What features should I expect in an imagery service?

First and foremost, you should expect performance; the imagery should load in under 1 second. You should also expect a variety of administrative controls to manage authorized users and secure access: knowing who is using their data is important for many agencies. Finally, you should expect usage tracking and reporting capabilities: these allow you to implement cost sharing or charge backs, and can be used to calculate the ROI of your investment.

What is the best way to manage and serve your imagery data?

Storing imagery in the cloud as pre-cached data in the form of tiled pyramids delivers high-performance with low storage cost. Cheaper cloud storage options are available for imagery that are accessed infrequently. This approach plus fast imagery streaming services, like Giza, makes it possible to serve vast amounts of data to individual users while monitoring usage and controlling access.

Giza is a Node.js application that allows you to stream tiled imagery data from the cloud at blazing speed. Giza is raster and vector compatible, and supports OGC-compliant WMS and WMTS web map services.
