Re: MI Help!!! how to translate Arc/Info GRID image to be used in MapInfo
+AD4- Hello, there +AD4- +AD4- I have a Arc/Info Grid image which is a fold of files and I'd like to be +AD4- used in MapInfo as either Grid layer or Vector layer. I have tried +AD4- ArcLink but it seems ArcLink does not support GRID format. It simply +AD4- skips the GRD section in +ACo-.E00 file where has all raster data. +AD4- So Is there anyone over there know any solution for that? +AD4- Thanks in advance. +AD4- You could try using ArcView with 3D Analyst if it is available to you. You can convert the grid to a shapefile which I think if memory serves me correctly, will create the cells as polygons. The Universal Translator should do the rest for you. Can you also not try to convert the grid to a vector file from within ArcInfo itself, than translate the .e00 fiel? Don't know if this helps.

MI Selecting by Coordinates
Is there a way to select a feature using co-ordinates. Understand that the centroid functions return coordinate values I can use, but if I insert these values into a variable, is there a command for selecting a polygon or whatever where a polygon contains those coordinate values? E.G. something like select map.obj, map.attribute where map.obj contains x and y? I am getting the x and y via the CommandInfo function. - Tony Elson GIS Consultant Geographic Technologies Limited PO Box 6015 Wellesley Street, Auckland, New Zealand Ph: +64 9 379 2061 x107 Cell: 025 278 4896 Fax: +64 9 379 2044 Email:[EMAIL PROTECTED] [EMAIL PROTECTED] URL: www.gtech.co.nz -- -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]

Seems a little flaky at times but on the whole, I have my reports going OK. I am running v5.0 (or 5.01) and by the looks of all of the reports stemming from those who have upgraded to 5.5, I am staying put. 5.0 seems eminently more stable.

Way to slow (which may have something to do with my underlying data structure). It was quicker for me to export the data set(s) via UT and do my processing in ArcView. The geo-processing tools in AV are far more advanced, easy to use and just that much faster. A personal opinion only, but I would be interested in reading some others' comments on MI's geo processing because my experience is admittedly limited, which could therefore cause my vision to be rose coloured.

It does - quite satisfactorily. MI and AV are quite useful as data integrators. --- Tony Elson GIS Analyst Geographic Technologies Limited PO Box 6015 Wellesley Street, Auckland, New Zealand Ph: 64 9 379 2061 x107 Fax:64 9 379 2044 Mobile: 025 278 4896 Email: [EMAIL PROTECTED] [EMAIL PROTECTED] -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
MI Building new tables on the fly
We are using data that is structured around the use of numerous tables. However, in Mapinfo as opposed to other GIS, building new layers or tables based on selections that are joined to other tables is laboured - unless I am not doing something right. Mapinfo won't allow selections on dynamic joins that are not "base tables" (i.e the concept of a database view or table definition isn't available). The user has to make a copy of the selection (i.e. save copy as) then build the next stage in the query to create a new table or layer. This does not seem to me to be particularly efficient. Does anyone have any ideas on building temporary or permanent tables on the fly without adding to the existing data sets with an "intermediate" layer, other than creating a "flat" table.

MI Altering Objects in Layouts (Text Objects)
Apologise in advance if this has been covered before and I'll admitt that my experience in MapBasic is limited. Basically, I have a layout. I want to automatically update some text in the layout. I have been able to identify the text I wish to change via the "fetch" and "objectinfo()" commands in my very basic .mbx program. However, I am having major difficulty trying to use the "Alter Object" statement. Since (or as I understand it) that the Alter Object statement requires an object variable (therefore referenceing and object or more specifically in my case, a text object), I have tried using the create text into variable command (even though the text is already there) So, my program looks a little like this: ..create text into variable myobj txt_var . etc 'where txt_var is a variable of the existing text. then I go: Alter Object myobj info OBJ_INFO_TEXTSTRING, "New Text". Obviously, I have something fundamentally wrong somewhere and I am not convince that the create text into variable command is the correct way to go. Are there other options?
