Hi I have one very big TIFF file which I want to seperate into many small tiff files. Is there a easy way to do so in ArcGIS 10.1? I saw the tiled map service functions but I am not sure if they do exactly what I need. I am sure there is a very easy way to do so. Thanks

Xander Bakker thought of that as well but as I use data driven pages I cannot change the settings for the extend. I also tried to set the extend to "fixed extend" before creating the DDP, but it still will Switch to Current Data Driven Page and move around within the extend

Thanks, I managed to get the desired layout. However, when I generate the 600 maps, all the maps are just somewhere random within the data frame. Is there a way to have all the maps at the same position, like in the center of the map page?

Thank you FC Basson and Xander Bakker‌ I read the Information but I could not figure on how to create these maps when I have one Shapefile with several different species in it. Is there a way to show each species seperately with the same map extend map with several other layers together like forest or water bodies? Also I could not set the size to A7.

Hello Anyone knows how to automatically generate over 600 Maps (Size A7) in ArcGIS? I heard of Mapbook Generator but I dont really understand how to apply it. I use ArcGIS 10.2 Thanks!

Seems to work (for most of the cases) when I change my field type to string! thanks!

Thank you! I am not quite sure how to handle the second and third field Trim(Mid(Split( [SURVEY_ID] , "-")(2), 1 resp. the 3rd field InStr(Split( [SURVEY_ID] , "-")(2), "(") - 1)) I guess SURVEY_ID has to be replaced with the original sourcefield Name? . I see what trim and mid do but not what the (2), 1 stands for? Also i get an error when I try to run it in the field calculator..

Thank you it seems to work! Allthough not when I have a case with text like this K1-10-67d (street) For the last two fields I get a 0 instead of a 10 and a 67d I ve no Phyton experience at all (yet)

I have an Attribute table with several attributes One of the attributes has the fields K1-10-11 K1-10-46 K1-10-46c K1-10-67d (street) I Need all of the elements from the field as seperate attributes eg an Attribute with K1 K1 K1 another with 10 10 10 and a last one with 11 46 46c 67d (without text) I cannot do this manually. Is there a way to do this in ArcGIS 10.1 ? Furthermore I am wondering if it is possible to connect attribute tables with Excel tables without loading the Excel tables (csv) into ArcGIS? Thanks!

Hello, I have two roadnetwork shapefiles which represent the same roadnetwork but are acquired with different methodes and therefore are not on top each other. One Network has Information about the road pavement (coloured shapefile) and I want this Information to be on the other road Network (red shapefile). Is there a Methode on how to do so? A buffer or nearest neighbours does not work because the road intersections will get wrong pavements (see attached Picture) Thanks!

thank you.. I think you got my question correctly, but can you explain me a bit more in detail how this works? which tool do I use to loop through all the polygons? and how can you automatically select the polygons within the polygon? and is it possible to save the summarized area in a table, with information to which mother polygon it belongs too? Maybe I started off wrong from the beginning. Let me explain in more detail. My goal is to calculate the fractions of the red polygons (see screenshotI) per raster cell. (screenshot shows only a small part of the whole dataset). Therefore I need to know the area for all red polygons per cellpolygon. I performed "raster to polygon" and got a lot of single polygons (beige squares) with GRIDCODE (attribute table). The former raster cells (which are polygons now) can contain several different fire polygons for which the area per cell must be calculated. I desire a table with cellpolygon ID (GRIDCODE) and the summarized area burned per cellpolygon.

I read similair questions but I couldnt figure out the answer yet.. What I have: -A fire polygon set with information about each year and the area -A second polygon set consisting of a lot of small polygons I did an identity overlay to get the fires per small polygon. Then I created new layers for each year. Now I have the fire polygons for all years needed per small polygon What I want: I need to calculate the area of the fires for every small polygon (per year). I know how to do this manually (select all fires in small polygon and go to summarize area) but since I have a lot of small polygons I need to do this automatically. Any suggestions on how to do this? I read about the Geospatial Environment Model option (but I cannot make it work) and about the Hawths Analysis tool which unfortunately is not available for ArcGIS10 anymore. Thanks for the help and suggestions!!

It seems to work!!! Thank you a lot! (Althoug I had to take the positive values for northing and easting, without "-") But how can I be 100% sure that the data is aligned perfectly? Also I am wondering if the raster still can be used for analysis and overlays with other raster since the squares are not actual squares anymore now because of the whole reprojection process? I am sorry for all these questions, but I am not an expert in ArcGIS!

‎03-07-2014

I managed to get the data close to my desired projection but however what kind of false easting I apply, I cannot align it. I attached you a screenshot on how it looks like now.. can u give me a guess on what number I have to enter? Thank you a lot!

‎02-24-2014

Thank you very much for your helpful answer!!! I think the coordinate shift is the only solution I have left over, however I couldnt make it work yet.
