Let me Know if this helps and how to prceed. I can get a polygon of the whole area with white part inclueded no problem from the footprints. Just the actual picture part not the white part. It is critical that the end polygon does not cover the white area in the photo. Moreover, to ESRI users, the attractive is that ENVI 5.0 provides 'seamless�? integration with ArcGIS.įor example, object-oriented �?rulesets (*.rul)�? from desktop ENVI can be run as an ENVI tool inside ArcGIS 10.x, to effectively extract features from rasters, which is just like �?rules (*.cga)�? from desktop CityEngine can be run in ArcGIS 10.2 to generate 3D city models from GIS data. Then, run one of �?raster to vector�? tools.Īfter that, many �?cleanup�? are also required, in order to get �?meaningful�? outcomes (points, polylines, or polygons).Ĭertainly, if directly converting �?raster to vector�?, it will take forever and also get �?un-meaningful�? results.Īs a reference, ENVI with �?Feature Extraction�? (5.0 SP3) has this efficient workflow with advanced algorithms to convert 'raster to vector', which is similar to ERDAS Objective. �?Grouping�? on above-classes or segments also advisable Classification or segmentation on raster image (no matter how many bands, 1~multi~hyper) must be done first Ģ. As recalled, also OK with 10.0 SP5.īut, before running any tools on �?raster to vector�?, something more need to done firstly, which could be referred to the general workflow below:ġ. I have tried it on small images big images single tiles and the same result the tool just will not work.Īny ideas and anyone know how to register this issue with ESRI? I have even used my work mates pc and ran it for 8 days and nothing. I have left the tool running all weekend and com back on monday and the tool is still going. We can not get the raster to polygon tool working. Ok this is the second time I have posted on this topic and I am reposting because this is having a massive impact on our work.
