    ENVI to Arcmap

    Ghazal
    By Ghazal,
    Hi all, This is my first time using ENVI and I have applied atmospheric corrections. These are the steps I took: 1- Radiometric correction 2- FLAASH atmospheric correction 3- To eliminate the Negative values and make them between 0 and 1 in data values, I used this formula:  (B1 le 0)*0+(B1 ge 10000)*1+(B1 gt 0 and B1 lt 10000)*float (b1)/10000 When I export the corrected later to TIFF, it will be in a 3 band composite but I need single bands to be exported as TIFF so I

    GlobalMapper 21.1 WFS GML problem

    Capricorn

    Hi people, When I connect to a WFS from GlobalMapper 21.1, a GML file with swapped coordinates is downloaded (northing-easting) and GlobalMapper reads these coordinates as they are easting-northing. Is there any workaround for this? ArcMap reads this WFS normally using Interoperability Extension without telling SRS axis order. GlobalMapper doesn't have any option to chose SRS axis order.

    By Lurker,
    Current u-blox GNSS platforms — from u-blox M8 and beyond — support the recently completed BeiDou navigation satellite system modernizations, improving the availability of GNSS positioning services. The opening ceremony of the BeiDou-3 global navigation satellite system (GNSS) was held in Beijing on July 31, officially celebrating the expansion of coverage offered by the critical Chinese space infrastructure to a global user base. As a global supplier of GNSS positioning and wireless c
