• What is OWGIS?

    OWGIS is a Java web application that builds web interfaces that contains dynamic maps. These interfaces contain many features like ....
  • Streamlines

    Newest version of OWGIS can generate streamlines to visualize currents, winds, or any other vector field.
  • Identify Features

    Depending on the layers that are being visualized by the WebGIS site, you can access its data at any location by simple clicking on the map.
  • Time Series

    If your data varies on time, OWGIS takes advantage of the ncWMS servers and provides time series from the time range selected through calendars.
  • Download as KML

    Just one click and any of your layers will be downloaded as a KML file, which can be visualized in other clients like Google Earth.
  • Depth Selection

    OWGIS builds a nice paginated window for selecting different z-axis of 3D layers.
  • 3D View

    3D view using WebGL with the Open Source software Cesium.
  • Vertical Profiles

    For 3D data served through ncWMS servers, OWGIS makes the proper requests to generate vertical profile graphs.
  • Color Palettes

    When the main layer is being retrieved from a ncWMS server, OWGIS builds the necessary web content to allow the user selecting from the available color palettes on the server.
  • CQL Filtering

    The interfaces built with OWGIS allows filtering the content using the Contextual Query Language. With these feature scientist can easily filter data.

What is OWGIS?

The OWGIS (Open WebGIS) is an OpenSource Java Servlets web application that creates WebGIS sites by automatically writing HTML and JavaScript code. The WebGIS sites are configured by XML files that define which layers will be displayed on the maps as well as the texts to be used on the interface. OWGIS's most notable features include animations, veritcal profiles and vertical transects, various color palettes, dynamic maps, downloadable data, and multilingual interfaces. All these features are created automatically without any additional web programming. 

Unstructured meshes!

Thanks to ncWMS2, now we are able to visualize output from unstructured meshes! Take a look at the following link that shows data from the coastal model ADCIRC ADCIRC and OWGIS.

Streamlines in OWGIS!

The next version of OWGIS will display vector fields with live streamlines! Following the ideas of Cameron Beccario and his great world visualization tool earth, OWGIS is now able to display winds and currents as streamlines. Besides the initial idea of Cameron, OWGIS changes the resolution of the data depending on the area been visualized... if you zoom in you get higher resolutions. It also allows for displaying the streamlines together with animations forming path lines that follow the vector fields through time. Finally the streamlines can be displayed at different depths if the data contain multiple depths.

As an example take a look at this awesome project that shows the global currents from the HYCOM ocean model using OWGIS: Link


ncWMS 2 is here to stay! We finally have support for ncWMS 2, this means that we can have streamlines natively from any vector fiedl served from ncWMS 2. In order to use it just add the following attribute into your layer declaration ncWMStwo="true". And remember to download the latest version of OWGIS from our git repository: OWGIS GitHub

OWGIS 2 Beta

OWGIS 2 Beta is Out!

OWGIS has been refactored to use OpenLayers 3, CCS3, canvas animations and more!
In addition to these new features, the configuration of OWGIS 2 has been noticeably modified from the previous version. Additional information on OWGIS 2 can be found here. We will start updating this website to include tutorails for OWGIS 2. The following image shows the new look for some of the controls in OWGIS 2:

3D view in OWGIS!

We are finalizing the new version of OWGIS. We will update the documentation soon! The new version allows the maps to be displayed in 3D using the Cesium Open Source project. You can enable the 3D view by clicking the icon on the toolbar.

Test this new feature at Global Hycom.

OWGIS Published!

The first paper of OWGIS has been published

You can see the paper here at Environmental Modeling Software!
Please reference the published paper in any other publication which uses OWGIS to create Web GIS sites.
