Hi all, I have a Slope ratser (xyz data) of a big area. I need to export just a small part of this area in order to send to a client the xyz data just for the selected area. How can I achieve this? I have ArcGIS 10.2 and just SA extention tool. Many thanks Francesca ... View more

Hi all, I reckon I have lots of gaps about carthography but normally I do not struggle too much in converting coordinates. I have to plot some coordinates in ARCGIS. They are in the format below: 43°31.4, 1°46.4 First of all if I tried to add a point (using Go to XY tool) into GIS just to see where these coordinates are it show them in the wrong place. Normally when I want to convert coordinates in easting and northing to be able to plot them in GIS I do: (min/60)+degree If I do the above conversion it gives me the metres and if I plot them in GIS they are shown exactly where the other "Go to XY" shows me. That is why I believe my conversion is ok. What should the problem be? I am really confused and I do not know any other trick to make the job Many thanks F ... View more

Hi all, I have to send some data to a company who makes numerical modelling. they asked for DTM data. I have a folder called DTM which has few files in it with the .adf extention. Is anyone aware of if this kind of file extention is good for a numerical modelling? If not should I have to look for a different kind of files? Many thanks, Cheers, F ... View more

Hi all, A while ago I asked how  I could interpolate some contour lines (bathy and isopachs) with ArcGIS 10.2 Spatial Analyst and I have been told to use the tool Topo to raster which did the job! I have just a concern about what I got. basically I have a cable route and the bathy contour lines as well as the ispoachs lines; Once I use topo to raster it looks a bit odd that they cover a huge area outside of the cable corridor and I d not know if this is due to some parameter that I should have set  or it is like it is. For instance the screenshot below shows the cable route (in red) where they did the survey. Along that route I have either bathy contour data and isopach lines. Then using topo to raster I get the pic below and I am surprised that they cover a huge area outside the red line. Do you have any suggestion? many thanks  and have a nice day, F ... View more
