You don't need a hex editor to create a MAPINFO lump. This lump is simply a plain text file that you insert into a wad which can be read by some source ports. Hexen was the first engine to use this lump, but it has sort of evolved over time, meaning what you can do with it depends on which source port you are designing the wad for.
For ZDoom's implementation, you should either start here or open other peoples' wads that use MAPINFO and look at how they are done there. You might also do a forum search for "mapinfo".
There is no Doom 2 MAPINFO. It's all hard-coded. (Except of course for ports which externalized it.) Anyway, do not expect to open doom2.wad in the lump editor, and find a MAPINFO lump you can edit. There will not be one. Also, you shouldn't edit IWADs anyway. It's a bad idea.
If you mean a custom IWAD, that's not a good idea, but whatever. You should do a custom wad file that contains only the stuff you added or changed, and load that in addition to a normal IWAD. Since you're talking of MAPINFO, a source port like ZDoom offers you clear and simple instruction on how you can autoload stuff so it's always there, and you won't be able to make the difference between that and a modified IWAD.
i Need help in mapinfo. We are doing Raster based GIS and cartographic modelling.I need to create a 100mX100m grid in mapinfo, but i'm not sure what extents i have to set for going further. Object type: Closed RegionsSmoothness: 0Spacing Between lines is 100 meters, and projection set to British coordiante system..please help me to make the grid.
It looks like you are using the 'Grid Maker' tool supplied with MapInfo based on the parameters you specified in your question. The extents are simply the minimum and maximum coordinates of the area you want covered by the grid. When you draw the rectangular area for your grid, these values are auto populated based on the rectangle you have drawn. If you want to manually adjust or change that area then you can do so by changing those values. So, let's say you want a grid which covers the area between 0,0 and 10,10 you would set your extents as:
Ive been trying to find feature comparison data between AutoCAD MAP3D and GIS software such as Mapinfo and ARC GIS but it seems hard to find. Can any AutoCAD MAP3D users here give me some advice on how the GIS capabilities of AutoCAD MAP3D differ from those of these other GIS products.... is AutoCAD MAP3D a fullly functional GIS package?
or ... in some cases it's hard to get labels as text-objects in case of high number of polygons (Map3D gets then slow on screen) and sometimes the intelligence of Map3D is to high to hold a text within it's polygon (well there are workarounds for that).
I concur with everything Alfred stated, just add that labeling features with attributes may be easier in ESRI.
The other main differeance AutoCAD Map3D has 3d build in, the last version of ArcGIS I used it was an add module that you paid extra for.
Alfred mentioned a plotting advantage for Map3D, and I have to agree that the multiple layouts is a huge advantage, but if you ever need to do a mapbook, (as some of us still do once in awhile), then the data driven pages in ArcGIS beats Map3D hands down.
I am primarily an ArcGIS user but actually started with CAD and I while I prefer ArcGIS for Making actual maps I do greatly miss the geometry editing ease of AutoCAD. Now I have Map 3D and am just getting into learning how to use it. The ribbon based layout is different from what I learned on (14 and 2000) but that will be a minor issue overall. Me I plan to use a blend of the two to my best advantage.
I use arcmap basic and Map3D. agree with all the comments so far. one area not mentioned is tranferring data to field computers and GPS. I fnd that Map is more agreeable to incoming data collected in the field as it can handle a larger variety on input formats and actually get the georeferencing right. Esri is easier to make a map look good and get it on paper but thats is only because not everyone will break the paper trail and go to electronic gizmos. Terrible thing to say for a forester making a living growing trees to make paper
The most important part of either of these programs and probably mapinfo which I have looked at but never took to is data preparation to get the required or expected results from the GIS. So look at the far end and output and make the data input so you can get there. the old GIGO thing.
Hi I have been using AutoCad since the old 10 version for DOS! I have to agree that doing edits, cleaning drawing, using blocks and using COGO is a snap in Autocad Map 3d. I started using ESRI products for about ten years and have found doing layouts with analysis is much less tedious in their product. Usually I will create county wide layers in Autocad, do all the edits, which it does in double precision, and add the base attributes that will attach to a database in Arc, and then ship that out in a shape format that has the coordinate system attached to that. The shapefile is then manipulated in to fit the visual effects required by my users, which use ArcReader, a rather handy free program from ESRI, to do queries and some base manipulation. Making the final map in Arc's layout view can be best described as a balance between insanity and "you've got to be kidding"
I have brought in shapefiles that need many changes in Autocad for the simple reason that it is so much easier and straight forward. When you do this sort of thing you will find the snaps in Arc, which seems to be single precision, will create a huge amount of overshoots and gaps. Fortunately, Autocad has a cleanup tool that does this in very short order. That makes for a whistle clean file!
