InfoTop: Information of MiraMon topological files

Direct access to online help: InfoTop

Presentation and options

This program allows reading data from binary vector files of points, arcs, nodes and polygons, which are topologically structured, in an intelligible way from DOS sessions. Under Windows, this data can be graphically consulted with MiraMon in a more friendly way, but if you want to know some internal value or you want to debug some errors in the topological file, it can be better to use InfoTop. Top-MiraMon vector files are also known as structured vector files.

The program allows the following options:

InfoTop (points - option 1)

InfoTop (archs - option 2)

InfoTop (polygons - option 3)

The first page of information shows a list of the files linked to the requested file. If any of them is lacking, the program notifies it; if the lacking file is not essential for the program operation, it is allowed to continue.

The second page gives information on the files' header. They show the number of entities (graphic objects) and the global bounding rectangles of the files.

The third page is a menu that allows:

In the case of arc or polygon files:

1 Visualization of an arc.: You can see all the information contained in the ARC file but the vertices. You can also see the coordinates of the initial and final nodes. If you have selected a polygon file the right and left polygon indices of the arc are shown.
2 Visualization of a node.: You can see the number of arcs that converge to a node.
3 Visualization of the vertices of an arc.: You can see the coordinates of all the vertices of an arc.
4 Visualization of polygons (only if a polygon file has been indicated): You can see the general information of each polygon contained in the POL file, as well as the arc identifiers of the polygon. For each arc it is shown whether the arc belongs to the interior or the exterior border of the polygon, if it is a final arc of an elemental polygon (ring) and if, in order to build the polygon, it is required to list the arc coordinates in the original order or in reversed order.

In the case of point files:

1 Visualization of the point coordinates from a given point on.

In all cases you can also view the database. There are two options:

1 Visualization of the database fields.: A list of the field names of the main (principal) and associated tables is shown, along with their relationships, and if they are declared visible or not in the REL file.
2 Visualization of database records.

Syntax

Syntax:

InfoTop 1 PntFile
InfoTop 2 ArcFile
InfoTop 3 PolFile

Options:

1: Points file information.
2: Arcs information. Any information about the polygons will not be shown.
3: Polygons information. Information related to arcs, nodes and polygons will be shown. If the arcs file has ever been cycled, we recommend using this option even to view arcs since the information given will be more comprehensive.

Parameters:

PntFile (Point vector file - Input parameter): It is the point vector file from which we want to obtain the information.

ArcFile (Arc vector file type - Input parameter): It is the arc vector file from which we want to obtain the information.

PolFile (Polygon vector file type - Input parameter): It is the polygon vector file from which we want to obtain the information.

This program works with files of v. 1.1
