Before reading this article we recommend you to familiarize yourself with the method of obtaining vegetative index maps using GIS Sputnik Agro. There is a step-by-step instruction below. If you previously performed the NDVI calculation photoscaan the Sputnik Agro and you have a Photoscan project with the uploaded data, skip this section.

Import aerial photos using «File» — «Import» — «Aerial photos Select the folder, containing the photos and the georeference file. In «Layers and Objects» the appropriate object will appear.

If it is required to convert all the aerial photos, select the « NDVI converter» from the context menu inside the «Layers and Objects» panel:. If it is profeesional to process only a part of the flight, select the aagisoft area with the «Rectangular frame» tool agisoft photoscan professional ndvi free call the « NDVI converter» from the context menu by clicking on the aerial photos icons:. In this manual an example agisoft photoscan professional ndvi free use of the PhotoScan raster calculator is considered; the only combination of channels that should be marked in this window is „pseudo-RGB”.

Resulting files are three-channel bit TIFF ndvo. After the completion, several new objects will appear in the «Layers and Objects» window by the number of selected checkmarks. Select the photos set from the « rgb » subfolder. In «Tools» menu select «Create PhotoScan project» or in the context menu by right-clicking on the layer. A detailed manual on working with Agisoft PhotoScan can be found in the user manual. Therefore, we list the general processing steps without a detailed description.

If the „Create PhotoScan project” function was used in GIS Sputnik, then after opening in Ссылка на подробности a separate chunk will be created in the project, with added seus shaders minecraft windows 10 free and imported georeference.

Survey data which is obtained with the modified for infrared surveying camera is suitable for building the height field. If the detailed height map is required, it is reccomended to build the dense point cloud. If the height agisoft photoscan professional ndvi free is nor required, then this step may be skipped. Regardless of whether the height field will be used in the future ndvk not, it is necessary to perform build, because the agieoft is used for the orthophoto creation.

In the project tree, select the orthomosaic. If the image photlscan too dark, use the „Set brightness” function. This is a visual agisoft photoscan professional ndvi free, which does not affect either the result of raster transformations, nor the result of export. On the first tab « CIR calibration » no actions are required. On the «Transform» tab formulas agosoft raster operations are defined. Further, it is assumed that the photos are taken from Geoscan Agro with modified Sony A camera with installed red filter.

In this case, the red channel corresponds to channel B1, and the near-IR channel corresponds to channel B3. Click the «Palette» tab. By default, a single-color paletter is used. For working with vegetation indices, the NDVI palette is used. Specify the limits of the palette’s range of applications by selecting a part of the histogram with the mouse or specifying them in numerical form.

If the histogram is not visible, click the button „update”. If the NDVI index is used and the range limits are agisoft photoscan professional ndvi free correctly, then the open water will be colored in shades of blue, the open soil will be in shades of brown, and the photosynthetic vegetation in shades of agisof. As a colored image. To do this, specify the „Index color” in the „Raster transformation” parameter in the 10 pro differences free export dialog.

The images obtained in such way are suitable for displaying even in standard viewers. As an indexed image. In the orthomosaic export photosczn for the „Raster transformation” parameter, specify the „Index value”. In this case, the palette is not applied to the raster, and if necessary, the узнать больше will need to be performed by the used GIS.

If agisoft photoscan professional ndvi free is required to convert all agisoft photoscan professional ndvi free aerial photos, select the « NDVI converter» from the context menu inside the «Layers and Professiohal panel: 3.

If it is required to process only a part of the flight, select the desired area with the «Rectangular frame» tool and call the « NDVI converter» profesxional the context menu by clicking on the aerial photos icons: 4.

Select the desired area on the calibration plate in agisoft photoscan professional ndvi free appeared window. Clicking the «OK» button will start the photos conversion.
