Inside some paragraph include one sentence with general information about software.
The MDT ( mdt ) file extension is used by the GeoMedia Access Database Template. This template is a file used to create and store geographic data layers within the GeoMedia Access Database. The MDT file defines all the attributes, values, and layers of a data set, and stores them in an Access Database.
MDT files are similar to other GeoMedia template file types, such as GDD ( gdd) and GDT ( gdt) files. GDD/GDT files are Data Driven Projects created in the GeoMedia Professional software application while MDT files are Data Driven Projects created in the GeoMedia Access software application. MDT files can also be used in Intergraph Geomedia Professional.
Structure of An MDT File
An MDT file contains several individual "chunks" of information including the "general" section which contains settings for the project, a "map title and summary section, the themes associated with the project, the tables found within it, and the links between them. Each of these sections are defined using Microsoft Access-style syntax and databases. MDT files also contain metadata about the project, such as a project name, its author, or its date of creation.
Using an MDT File
MDT files are primarily opened and edited using Intergraph GeoMedia Access. The program allows users to view the information stored in an MDT file, modify it, and export it to another format such as KML ( kml) or GPX ( gpx) for use in other mapping or geographic information system (GIS) programs. Other related file types that work with GeoMedia Access Database Template include MMF ( mmf) files, MDS ( mds) files, MNU ( mnu) files, MXD (
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .MDT) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .MDT extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .MDT file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .MDT extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .MDT extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .MDT file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .MDT file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .MDT file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .MDT file) will be extended to the maximum.
It is also good to check
- if the .MDT file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
