The definition of workflows and models related to GIS and geodata is a logical step towards the automation and standardization of processes. In this context the ETL term is often introduced. ETL describes the process of data transformation: Extract, Transform and Load. There are a lot of modeling and ETL tools, e.g. FME, GeoKettle or Geospatial Talend.
A short introduction to ETL and and Spatial Talend can be found in our Blog.
We support you in automating GIS processes:
- Creating templates with different ETL tools (FME, Geosptial Talend, GeoKettle …)
- Preparation of legacy data (e.g. digitizing, georeferencing, vectorizing of maps, arial images)
- Data type conversion, transformation of spatial reference systems, geocoding
- Shell scripting or Python scripting for recurring workflows
INSPIRE is based on the infrastructures for spatial information established and operated by the 28 Member States of the European Union. The Directive addresses 34 spatial data themes needed for environmental applications, with key components specified through technical implementing rules.
To ensure that the spatial data infrastructures of the Member States are compatible and usable in a Community and transboundary context, the Directive requires that common Implementing Rules … are adopted in a number of specific areas (Metadata, Data Specifications, Network Services, Data and Service Sharing and Monitoring and Reporting).”
(cited from http://inspire.ec.europa.eu/)
To realize the directive the standards defined by the Open Geospatial Consortium (OGC) are used or implemented. The standardizations pursue the aim of interoperability, that also implies the seemless cooperation between different systems, techniques and organisations.
The standardizations of OGC describe numerous space-related web services, e.g.
- Web Map Sercvice (WMS)
- Web Map Tile Service (WMTS)
- Web Feature Service (WFS)
- Web Coverage Service (WCS)
- Web Processing Service (WPS)
The geodata web services are published by a mapserver. There are a lot of propietary or free mapserver software, e.g. GeoServer or MapServer. A comparision of broad range of mapservers has been published on Wikipedia.
We support and consult you with the conception and the standardized provision of your geoinformation by an individual geodata management and the creation as well as support of appropriate server solutions and the corresponding infrastructure.
- Provision of geodata from public administrations and services
- Expansion of the usage potential of your data
- Provision of spatial meta-information
- Search for geodata and data services
- User and right management for services, geodatabases, …
- Provision of individual OSM services
Our competences here are especially in the area of Open Source solutions.
The currently available desktop GIS software (open source as well as propietary) offers a variety of sophisticated functionalities to process geodata. Nevertheless, the desktop GIS programming of application modules, i.e. a GIS application tailored to a specific field of work, is a recurring requirement. For industry-specific workflows, functionalities can be combined, superfluous functionalities can be omitted and graphical user interfaces can be individually designed so that effective work is made possible. Examples could be:
- GIS support for branch specific workflows
- individual graphical user interfaces
Known examples for specific GIS application modules are
- GIS for field work, monitoring campaigns, precision farming, …
- GIS for visibility analysis, location planning, geomarketing, power supply networks, logistics, …
VisDat geodatentechnologie GmbH supports you in the implementation of your individual GIS software:
- Programming of desktop GIS applications based on QGIS / PyQGIS, QGIS plugins and QGIS scripting
- Programming of external GIS interfaces as part of a superordinated system
- Interfaces programming (e.g. to databases)
- Support and further development of specific GIS applications
Basically, a WebGIS is a geo-information system that uses the runtime environment of the web browser. Compared to desktop GIS, it has the great advantage that it is not limited to a single workstation, but can be used by a large number of Internet users. WebGIS has established itself as a viewer for displaying geodata in a wide variety of industries. Furthermore, it is our goal to create business processes and workflows for our customers in individual solutions.
Another current requirement is the application of the so-called “responsive web design”, so that mobile devices can also obtain optimized content displays.
To build up an individual, customized geodata infrastructure we are offering our own geospatially enabled web server:
- OGC web services like WMS or WFS
- Geodata hosting
- Web processing services
- and much more
Geodatabases are very suitable for the storage of a large amount of data or high data volumes related to geospatial issues. This kind of spatially enabled databases operates with spatial data types and spatial indices. The implementation of spatial operators and functions allows the processing of geodata directly.
Examples for the usage of geodatabases:
- Management and storage of laser scanning data
- GDI for power supply, traffic sector, logistics, health care systems, ….
- Storage of any network data as topological data for further processing options (routing, node-edge models)
- custom-fit storage concepts for OpenStreetMap data
- Data management of specialised GIS applications, for example the link between a QGIS plugin to a geodatabase
- Geodatabase access from mapservers (WMS, WFS)
The category PostgreSQL / PostGIS of our blog publishes articles about issues related to geodatabases and PostGIS.
VisDat geodatentechnologie GmbH offers services around the conception, design and development of software related to geoinformatics, geographic information systems (GIS) and spatial information.
In close cooperation with our customers we develop the professional and technical requirements for individual GIS software. This also includes the analysis of the current state and potential analysis of existing systems.
Furthermore, we advise on the make-or-buy-decision when ordering software, i.e. the choice between in-house production and outsourcing.
Another important field of work is consulting and support in the search for relevant commercial and freely available geodata.
Examples for the professional use of geoinformation and GIS can be found today across inustries:
- Software for planning advertising campaigns (www.prospektmanager.com/)
- Visualization and presentation of water-management related issues (www.viewer.stoffbilanz.de)
- Route planning including various means of transportation (www.clickapoint.com/)
