Thanks everyone. Question answered. ... View more

Yes Neil, you are right. Everything is in the table. I couldn't export it into a shapefile before and that's why I wanted to find a way to join my table with the existing shapefile. But yes, the table with the routes was exported just fine on its own. Thank you very much Neil, Wes, and Chris. Quick question since it crossed my mind. If I had a shapefile with say for example 1000 sections and needed to keep only 50 of them (just by knowing the names of the sections), what's the best way to do it? ... View more

Thanks Neil, got rid of the spaces and the table is on. So the first part is achieved. Now, how am I going to relate this table with my initial shapefile? Remember that in my shapefile each section can be found once while in the table I created each section is found more than one times. ... View more

Thanks for the reply. It gives me a message saying: The table you specified does not have an Object-ID Field so you will be not able to select or edit the features in the resulting layer (apparently that's why my table is empty). However, I've got an OID Field set in my table. I am not sure how to proceed. ... View more

Actually, I've managed to isolate the preferred chainage lengths by right-click in the table in the TOC and Display Route Events (linear referencing as you said). However, the selections are visible in the map but the attribute table is empty. I've tried to join the newly created table (the one with the route events) with my initial shapefile that contains the sections as whole lengths. The join works, meaning that I get a new table that has all the information that I need but after the join no lines are visible in the map. And still, since there is no spatial connection I'm left with a table or layer instead of a new shapefile. ... View more

Fair enough Chris and thanks for the reply. What if I've got different distances to specify for each segment? ... View more

Thanks for the reply. So, on the left I've got a shapefile with sections and their lengths. On the right side I've got an analysed table with the same sections, although they appear more than one times. So, for section 1000A/1 I need to attach the value of 17 only in the chainage between 138.029 and 148.04. In addition, for section 1000A/11 for example I need to include the values of 16.8, 17.3, 21.8, 4.4, 22.9 and 15.3 in different chainages. The same occurs to more than 100 sections, so a manual way is not an option. ... View more

Wes thanks for the quick reply. So let me explain. I've got a map with the road network, where each section is represented by certain attributes (Section 1, Section 2, etc with additional info such as lengths, lanes, description etc). I am now processing some data in an Excel which contains the same sections as before. The point is that within these data, each section has more than one attribute values. E.g. In the shapefile Section 1 has a length of 2km. In the spreadsheet the same section has been divided into more than one "parts", according to the chainage (0-10m, 10-20m,.. 1990m-2km). Each "part" is associated with a different value, say for example from 0-10m there is a value of 1mm, from 10-20m a value of 2.5mm and so on. These values are the ones that I need to show in my map. However, I cannot find a way to give this spatial information to my table and create a shapefile. Of course, I can't join the tables since the relationship is 1:M and I'll lose the rest of each section's values. Does this help? ... View more
