In this tutorial, you can download sample Productivity Maps layers, and review sample applications, including: *... *... *...
Prior to carrying out these exercises, it's recommended to review the following articles: What is NDVI What are Productivity Zone Maps ..... -------------------------------------------------------------------- download crop history - //review information in different years //see a productivity map, what years info came from create directed sampling with structure for soil sampling – send to gps enter soil values → ph limiting factor do a prescription using 2tons acre lime → send layer with prescription
=== Download sample data === For these exercises we are going to download a sample dataset: 'Sample RS_FARM' (for Remote Sensing) For this purpose, you can follow the steps detailed in Download sample data, selecting 'Sample RS_FARM' as the initial dataset, which can be found under the 'Tutorials_en' folder: UDT1.jpg //change image
----
=== Exercise 01 - Review downloaded information  === The first step is to analyze all the information related with our sample productivity map.  ==== Review crop history and Vegetation index (NDVI) from previous years ==== Crop history is relevant to understand the resulting productivity zones maps, as described in this ......//add link Please download the crop history for the sample farms from this link .... //add link. By reviewing NDVI from previous months or years, we can see the correspondence between NDVI and crop history: The NDVI date can be found as part of the layer name. //put figure turn on layer ..... open crop history table that you previously downloaded.... //put figure of ndvi next to crop history the NDVI .... corresponds to the crops in year ....., we can see that fields .... had Corn planted, and fields ... had soybean planted. Please review this article  download crop history - //review information in different years //see a productivity map, what years info came from
#Double-click on the soils layer under the group 'Farm Layout' in the eferences Panel, on the left side of the screen.

#To label soil Map Units with attribute “MUSYM”, select the Image:GIS_gis_Edit_03_01.jpg  Edit cartography and layer properties tool. The Layer Properties screen appears. 
#Click on the Symbology tab, then go to the labeling tab, and check “MUSYM” as attribute. Click on 'Font options' and select a font size of 7, black letters on white back ground.
Also, use 'More Options' to place labels in the Position: Middle center.

#You can save to an image file or create a printout with the Print tool. Go to the Print tool icon Image:GIS_gis_Navi_08_01.jpg on the Navigation Toolbar at the top. The map layout preview appears. On the map layout, you can setup your title, move the north arrow, select references, save to a file or send to the printer, and other options. Click here to see full size


#Please review the different options available in the Print tool.

In our example, we are going to use the options:
. Save as 'map and references'
. Save file: sample print.jpg, as  a .JPG file

----
==== Create a soils table by exporting to a MS Excel spreadsheet. ==== #Click on the “Soils” layer in the References Panel to make it active.

#Select soil map units by clicking on the “Rectangle Selection” tool  on the left of the Navigation Toolbar, and drawing a window to include them.Image:LG_cnmp_cm_06.png

#Click on the Edit Selected Object Data tool  Image:GIS_gis_Navi_07_01.jpg. Once the information table is shown, click on Export, save it to your local disk, and the excel spreadsheet will be created. You can delete there the unwanted columns.

Exercise 02 - Create a map with field numbers and crops per field ===
==== Import sample data ==== In this exercise we are going to import sample fields that were digitized in the 'Fields_Producer' layer in this tutorial:  Using drawing and data editing tools If you have completed this tutorial and have saved the project, you can use that data for this exercise. Otherwise, you may import it into your project following these steps:
#Download the file 'sample_Fields.lay'  from this link, and save it to a local folder.
#Select the Image:GIS_gis_Edit_10_01.jpg  Backup Layers Tool to restore the .lay file.
#Click on the tab Restore, and then Click on Browse. A window will pop up for you to search for the 'sample_Fields.lay' file that you saved in your local disk in step 1. Once you find it, click on Open.

#The layer "Sample_Fields" contained in the .lay is listed. Select it to add it to the current project by clicking on the checkbox on the right.

#Click on Restore. The restoring process will start. During this, GeoAgro GIS will automatically compare the structures of the imported layers with the ones predefined by the system. When this process finishes, the following window will be shown:

==== Create a map with Crop types, with symbology and labels ==== Double-Click on the “Sample_Fields” layer to make it active and zoom to its extents

let’s review the attribute data of the Fields
#Select all the Fields in layer ‘Sample_Fields’ with one of the options from the Selection tools
#Go to the Query tool, and select the option 'Quey data by selection'.
Image:GIS_gis_Navi_07d_2.3.15_01.jpg

The attribute table for the objects you have selected will open.

You can see that some of the fields have numbers and crop types assigned Now, let’s assign colors and labels to the crop types Select the Image:GIS_gis_Edit_03_01.jpg  Edit cartography and layer properties tool. The Layer Properties screen appears. 
#Click on the Symbology tab, then choose the option ‘Classes’, since we are going to assign different colors to the two type of crops in the fields (corn and soybean).

Image:GIS_Symbology_2.3.9_03.jpgClick on the wizard at the right of the panel

CM4.jpg

#In the Classes wizard, choose: Identifier: CROP

CM5.jpg

#Then, assign colors to each type of crop.
In the Fill box (lower left), assign a orange tone for corn, and a green tone for soybean

CM6.jpg

#Then, assign labels to each type of crop
In the Label box (lower right), check the “FIELD_NAME”, "CROP".

#In the ‘More options’ link, select Position: Middle Center, separator: dash

CM8.jpg

#Choose the paint icon, to apply the label parameters to all classes (types of crops).

#Finally, you can change the layer’s transparency by clicking on the eye icon of the ‘Sample_Fields’ layer, and slide the bar to give a certain transparency

#Please review the different options available in the Print tool.

In our example, we are going to use the options:
. Save as 'map and references'
. Save file: sample print.jpg, as  a .JPG file
