GeoAtlas is the mapping environment for GeoGraphix that provides map creation and montage capabilities to its end users. The spatial data integration feature of GeoAtlas provides endless capabilities to clients with an enterprise GIS infrastructure. I am writing this blog post to provide an introduction to these capabilities and to encourage a discussion between users and the IT/GIS staff in the pursuit of producing high quality maps.
Esri® is the market leader in providing GIS software, services, training & research to almost all industries. According to Esri, “Enterprise GIS is a platform for delivering organization-wide geospatial capabilities while improving access to geographic information and extending geospatial capabilities to nontraditional users of GIS.”
Almost all large exploration companies already have an enterprise GIS infrastructure available. Such infrastructure is managed by a dedicated team, who is responsible for receiving data from all sources, in different formats and resolution, and in turn transforming them into quality maps while ensuring accuracy and maintaining audit trails. The correctness of the data and suitability of use is backed by the data owner, usually a domain person, and the GIS expert is only responsible for disseminating such data correctly. As ESRI is the market leader and is dominant in the oil industry, most enterprise GIS infrastructure consists of ArcSDE and ArcGIS servers as primary components. The rest of this post will revolve around this fact.
GeoGraphix provides state of the art mapping capabilities for the oil and gas industry. GeoAtlas is based upon ESRI technologies, but it uses the Blue Marble Transformation Engine for all coordinate conversions, which aligns it with the special demand of many exploration companies. These specialized mapping capabilities such as conditional & proportional pies, bubble maps, Z-Map file support, and high quality contouring make GeoAtlas the first choice of exploration companies producing quality maps for informed decision making.
GeoAtlas also provides the capability of importing data from the ArcSDE server. The spatial data filtering capability of GeoAtlas clips data within the area of interest (AOI) for performance optimization, and is capable of importing data from multiple versions of the ArcSDE server. As ArcSDE is limited to hosting data and does not contain themes and rendering details, GeoAtlas provides advanced rendering capabilities to our users to generate themes after importing data from ArcSDE.
Online map publishing is a vital part of enterprise GIS. GIS staff produce meaningful maps for improved decision making and publish them on the ArcGIS server. GeoGraphix provides the capability to load such maps directly in GeoAtlas as a layer (or a group of layers). The user can import as many map services as are required from the locally hosted GIS server as well as from online free and paid public sources. All these layers, blended with the GeoGraphix layers like land grids, topology maps, seismic navigation, well paths, production volumes, isochrones, isopachs, formation thickness maps etc., produce high quality hybrid maps very quickly.
GIS users know the significance of the .LYR file. It is the ESRI proprietary file format to contain data sources and their rendering details. GeoAtlas has the capability of importing and exporting this format very well and it opens a whole new arena of possibilities for producing and disseminating high quality maps across the organization.
* “An Enterprise GIS is a geographic information system that is integrated through an entire organization so that a large number of users can manage, share, and use spatial data and related information to address a variety of needs, including data creation, modification, visualization, analysis, and dissemination. In addition to providing users with GIS capabilities, Enterprise GIS is also made available to other software systems, including those dedicated to Spatial function or those that can usefully benefit from the inclusion of spatial information or processing.” (Source: Wikipedia)
