FAQ - GIS digitizing
now so easy!!
Find answers to frequently asked questions about the JDS GIS digitization.
We have geographical maps from
our area and want to convert these into a digital map.
To the graphical elements in our
map we want to add additional data relevant to the the objects in the map.
We have arial photographs from which new maps shall be derived. Alternatively the existing map shall be completed and brought up-to-date on the basis of these arial photographs.
We are a utility company and have several hundred maps on paper or transparent sheets describing the area that we supply with energy and our network consisting of cables and pipes. The existing maps include many colored and frequently revised entries. We would like to extract from these paper maps all objects from our supply network and blend them into the digital land base map. All operational lines, pipes and equipment needs to be digitized while a set of rules must be followed, like for instance a predefined positioning of the cable route within the street boundaries. As a result we want to get e.g. a CAD file containing an electrically interconnected cable route of our complete supply area, which we can import into our GIS system and connect this graphic data with other object data stored in the GIS data base. For the combined digital representation of our supply network with the landbase map the Gauss Krüger coordinate system has to be used.
We operate a transportation network work and do maintain many thousand green areas, which are located along our transportation network. Today these green areas are present on colored map sheets. For improved maintenance these green areas shall be administrated by a GIS. Therefore the green areas shall be digitized as polygons in a CAD file that can be imported into the GIS. Further the GIS shall be updated by object data, which today is contained partially in lists, partially in a data base.
The land utilization plan of our municipality is presently available as a colored map on paper. It needs to be transferred into digital form. Traffic routes, vegetation surfaces, power supply lines and pipes shall be captured as digital objects.
The communal development plan of our municipality is presently available on paper. It needs to be transferred into digital form.
Can JDS transfer map material, which is represented today in old coordinate systems, e.g. in Soldner coordinates into the widely used Gauss Krüger coordinate system?
What are the differences between CAD and GIS and what do they have in common?
GIS systems (geographical information systems) administer in connection with the geographical map equipment such as cables, pipes, rails and so on and the data related to these objects, like power specifications, maintenance data, etc.. The emphasis with GIS thus is on the administration of matching objects and data, while the accuracy and the constructional aspect are less important.
Historically GIS systems because of the need to store object data have been integrated with data bases prior to CAD systems. Although today also all important CAD systems feature an integrated data base. An important aspect with GIS systems is the generation of relations between objects and the map and the referencing of the plan to existing points of reference and coordinate systems. This topic of georeferencing and the transformation requires special functions in GIS systems.
Ever more operators of technical plants must both handle constructional and/or technical maintenance and engineering tasks, and at the same time need information about the location of the equipment with reference to the geographical map in their plants or networks, including equipment related data and specifications. Therefore CAD and GIS systems must be able to exchange data in both directions, whereby neither the accuracy nor the reference of the objects may be lost.

“The results of the JDS CAD digitization really convinced us!
We would already have saved a lot of time and money had we known of JDS SOMMER GmbH earlier. We can recommend JDS CAD digitization to all CAD users who desire nearly completely exact and complete conversions of existing plans and details into CAD files for very favourable prices!”
