I have a data set where many arcs need to be changed to straight lines. I have a report of the data set, showing which lines have anwanted radiuses, on the following form:
OID 3, Målemetode '<Ukjent>', Nøyaktighet '<Ukjent>'
Partnummer Punktnummer Nord �?st Høyde Radius
1 6651396,500 612318,560
2 6651399,907 612312,964
3 6651403,210 612307,540
OID 5, Målemetode '<Ukjent>', Nøyaktighet '<Ukjent>'
Partnummer Punktnummer Nord �?st Høyde Radius
1 6647679,520 617209,770 99,452
2 6647676,374 617231,726 99,452
OID 6, Målemetode '<Ukjent>', Nøyaktighet '<Ukjent>'
Partnummer Punktnummer Nord �?st Høyde Radius
1 6650282,000 609674,690 0,000
2 6650283,000 609673,440 0,000
The report gives object ID of the line feature (OID), "Målemetode ukjent" = surveying method unknown, "Nøyaktighet ukjent" = Unknown accuracy, "Partsnummer" (part number in a multipart feature, there should not be any in this data set), "punktnummer" = vertex number, "nord" = north, "øst" = east, "høyde" = height (the data does not have z values), and "radius" I assume you understand. 🙂
As you can see in the example, for straight lines, no radius is given after the east coordinate, and for circular arcs that we want to keep, the radius is a number not equal to 0,000. The radius of on a circular arc is given for both the start- and endpoint of a line segment.
Is there a way to make ArcMAP go through the report, find lines where the radius = 0,000, and then change the corresponding line segments to straight? I am not familiar with Python, but I have a feeling that might come in handy here.
Any ideas are appreciated! Regards, Turid
