The area of Counting is decisive for counting

Automatic counting and the degree of land cover are independent functions. When counting manually, a counting frame must first be created.

The desired raster file is selected in the raster drop-down.
The desired parcel plan is selected in the polygon layer dropdown.
A minimum distance between the counting frame and the boundary of the respective parcel can be determined with buffer (m). The value is in meters.
The dimensions of the counting frame are determined with the size of the counting frame (m). The values are in meters.
If the checkmark is set for Randomly rotated counting frames, the positioning within the parcel is rotated randomly and not based on the alignment of the parcels.

Click OK to create a counting frame layer. The name of this counting frame layer is made up of the name of the selected raster file and the ending _CF. This counting frame layer can now be used for manual counting.

The desired parcel plan is selected in the polygon layer dropdown.
The counting frame layer, created under Create counting frame, is selected in the counting frame layer dropdown.
With counting frame ID, the ID of the currently selected counting frame is displayed. You can use the arrow keys or an entry to jump to another frame. The currently selected counting frame is always marked in red.
Below the counting frame ID are two unoccupied dropdowns, which can be used to select an attribute from the database of the parcel experiment. Then the values of these attributes are displayed for the currently selected counting frame.
With Back and Next it is also possible to jump to the previous or next counting frame.

If a counting frame has been selected, a metering point can be set with the left mouse button or an existing metering point can be deleted with the right mouse button.

Note: If a click is made within a counting frame other than the one selected, no counting point is created, instead the system switches to this counting frame.

With number, the number of metering points is displayed within the selected counting frame.

With number (total) the total number of all counting points is displayed over all counting frames.

With OK a counting point layer is created, the name of this counting point layer is made up of the name of the selected raster file and the ending _CP. In addition, the parcel experiment in the database is assigned the respective number of meter points of the parcel or the number of meter points per m² of the parcel in the database with the attributes COUNTTOTAL or COUNTPERM2.[/text-with-icon][/vc_column][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” width=”1/2″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][image_with_animation image_url=”5998″ alignment=”center” animation=”Fade In” img_link_large=”yes” box_shadow=”none” max_width=”100%”][/vc_column][/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” width=”1/1″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][vc_text_separator title=”Counting automatically” color=”custom” border_width=”2″ accent_color=”#008e4d”][/vc_column][/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” width=”1/2″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][text-with-icon icon_type=”font_icon” icon=”icon-expand-alt” color=”Accent-Color”]

The desired raster file is selected in the drop-down raster.
The desired parcel experiment is selected in the dropdown polygon layer.
With buffer (m) each parcel can be buffered inwards by this distance and only the area within the buffer is evaluated. The value is in meters.
With Polygon ID, the ID of the currently selected polygon is displayed and you can use the arrow keys or an entry to jump to another polygon. The currently selected polygon is always marked in red.
Below the polygon ID is a dropdown occupied with default, here you can choose between various default settings for classification and processing. No default settings have been made for default. For plants, the setting is roughly predefined for counting plants and for flowers for counting flowers.

You can also create your own presets (symbol: add.png), overwrite existing ones or save current settings (symbol: save.png) or delete the currently selected preset (symbol: delete.png).

In the Classification tab, you can choose between two color spaces for filtering (HSL and RGB) and set the upper and lower threshold of the respective values (for HSL color value, saturation and brightness / for RGB red, green, blue).

You can also use the color field at Min or Max to take a color directly from the map. To do this, click on the color field that is marked in red and then on a pixel on the map, or you can drag an area with the left mouse button pressed. Then the color values of the pixel or the average values of this area are adopted as the lower or upper threshold.

Note: For raster files with only one channel (e.g. NDVI, grayscale) there is only the color gray and the upper and lower threshold can be set for this.[/text-with-icon][/vc_column][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” width=”1/2″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][image_with_animation image_url=”6001″ alignment=”center” animation=”Fade In” img_link_large=”yes” box_shadow=”none” max_width=”100%”][/vc_column][/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” width=”1/2″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][text-with-icon icon_type=”font_icon” icon=”icon-expand-alt” color=”Accent-Color”]

In the Processing tab, the classified areas can be reworked or optimized with various parameters. As soon as you switch to this tab, the display changes to a binary view (black and white image).
With Seven Minimum Width (Pixel) or Minimum Height (Pixel) it is possible to filter out smaller splinter objects since only contiguous objects with at least these dimensions remain. The values are in pixels.
With growing or shrinking it is possible to let the remaining objects grow or shrink to e.g. to connect split objects or to better separate adjacent objects.

Note: Several waxing or shrinking steps are also completely arbitrary in the order possible

At minimum distance (m), only objects are counted as such whose distance to the next object corresponds at least to this value. The value is in meters.
With minimum size (pixels) or maximum size (pixels), only objects are counted as such whose number of pixels is larger or smaller than these values. The values are in pixels.

Counting now counts all remaining objects within a polygon and the center of gravity of the respective object is marked with a point.
With Count (All) all remaining objects of all polygons are now counted and the center of gravity of the respective object is marked with a point.

Note: As with manual counting, it is possible to add more objects manually with the left mouse button or to delete them with the right mouse button.

With number the number of objects of the selected polygon or the total number of all polygons is displayed.

Screenshot: Automatically count dialog with counted points on the map and tab Classification selected.

If the checkmark for Overlay is set, the classification image or the black and white image is displayed. Without a tick you can see the original raster file again.

With OK a counting point layer is created, the name of this counting point layer is made up of the name of the selected raster file and the ending _CP. In addition, the parcel number in the database with the attributes COUNTTOTAL or COUNTPERM2 is assigned the respective number of meter points of the plot or the number of meter points per m² of the plot.[/text-with-icon][/vc_column][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” width=”1/2″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][image_with_animation image_url=”6003″ alignment=”center” animation=”Fade In” img_link_large=”yes” box_shadow=”none” max_width=”100%”][/vc_column][/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” width=”1/1″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][vc_text_separator title=”Coverage” color=”custom” border_width=”2″ accent_color=”#008e4d”][/vc_column][/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” width=”1/2″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][text-with-icon icon_type=”font_icon” icon=”icon-expand-alt” color=”Accent-Color”]I

The desired raster file is selected in the raster drop-down.
The desired polygon plan is selected in the polygon layer dropdown.
With buffer (m) each parcel can be buffered inwards by this distance and only the area within the buffer is evaluated. The value is in meters.
With Polygon ID the ID of the currently selected polygon is displayed and you can use the arrow keys or an entry to jump to another polygon. The currently selected polygon is always marked in red.
Below the polygon ID is a dropdown with default, here you can choose between various default settings for classification and processing. No default settings have been made for default. For plants, the setting is roughly predefined for the degree of coverage of plants and for flowers for the degree of coverage of flowers.
In addition, you can create your own presets (symbol: green plus), overwrite existing ones or save current settings (symbol: floppy disk) or delete the currently selected preset (symbol: red cross)

You can also use the color field at Min or Max to take a color directly from the card. To do this, click on the color field that is marked in red and then on a pixel on the map, or you can drag an area with the left mouse button pressed. Then the color values of the pixel or the average values of this area are adopted as the lower or upper threshold.

Note: For raster files with only one channel (e.g. NDVI, grayscale) there is only the color gray and the upper and lower threshold can be set before this.

All areas marked in white are used for the degree of coverage.[/text-with-icon][/vc_column][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” width=”1/2″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][image_with_animation image_url=”6004″ alignment=”center” animation=”Fade In” img_link_large=”yes” box_shadow=”none” max_width=”100%”][/vc_column][/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” width=”1/2″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][text-with-icon icon_type=”font_icon” icon=”icon-expand-alt” color=”Accent-Color”]

With the degree of coverage, the areas of all remaining objects within a polygon are now added together.
With coverage (All) the areas of all remaining objects of all polygons are now added together.
With coverage (m²), the covered area of the selected polygon or the total covered area of all polygons is displayed.
With coverage (%) the percentage of the covered area of the selected polygon or the percentage of the total covered area of all polygons is displayed.
If the checkmark for Overlay is set, the classification image or the black and white image is displayed. Without a tick you can see the original raster file again.
