| - | =====LESSON 9: Working with maps and tables iteratively===== | ||
| \\ | \\ | ||
| - | ==The aim of this lesson is to introduce the user to calculate the area of each source feature on Dinamica EGO. For this, we will calculate the area of each category of Legal Amazon Protected Areas map in the year 2000 and, next, to calculate biomass and Carbon Dioxide content in Biomass in high priority conservation areas within protected areas. .== | + | ====LESSON 9: Working with maps and tables iteratively==== |

| - | • Functors: Calc areas and Calculate map | + | |
| \\ | \\ | ||
| + | In this lesson we will use the functors **Calc Areas** and **Calculate Map** and the following files: | ||
| \\ | \\ | ||
| - | **We will use:** | ||
| \\ | \\ | ||
| - | - The protected areas map in the year 2000 (Guidebook Dinamica_4/Database/Protected_areas/protected_areas_2000.tif) | + | * The protected areas map in the year 2000 (''Guidebook Dinamica_4/Database/Protected_areas/protected_areas_2000.tif'') |

| \\ | \\ | ||
| \\ | \\ | ||
| - | **Let's go!** Initially, From the library window grab and place on the sketch the Load Categorical Map Functor, which are located in the Input/Output tab. Double click, and open the protected_areas_2000.tif file. | + | * From the library window grab and place on the sketch the **Load Categorical Map**, which is located in the Input/Output tab.

| - | Click on the Map Algebra tab from the library window, grab a Calc areas functor, place it on the sketch and connect the Load Categorical Map to them. The expression result is calculated as a real value and converted to the data cell type of the output map. | + | * Click on the Map Algebra tab from the library window, select **Calc Areas**, place it on the sketch and connect **Load Categorical Map** to it. The expression is calculated as a real value and converted to the same data cell type as of the output map. |
| \\ | \\ | ||
| \\ | \\ | ||
| - | Now you need to save the result to a file. For this, Grab and place on the sketch the Save Table functor and connect the functor Calc areas to them. Open Save Map, select a folder and write a name file to save (suggestion: Areas of Legal amazon protected areas.csv). | + | * To save the result to a file, grab and place on the sketch **Save Table** and connect the functor **Calc Areas** to it. Open **Save Table**, select a folder and write a suitable file name (e.g. areas_of_legal_amazon_protected_areas.csv). |

| - | Mark the eye button at the top of “Save Table” to viewer the results hereafter. | + | * Save and run your model. Click on the eye button of **Save Table** to see the result. |
| \\ | \\ | ||
| \\ | \\ | ||
| - | Save your model (Disk button on the main tool bar) and then run it by clicking on the run button (blue arrow on the main tool bar). | + | {{ :imagem69.png?500 |}} |

| - | **What is your model doing?** It is loading “protected_areas_2000.tif” file and then calculating the area of each category of Legal Amazon Protected Areas. | + | It is loading “protected_areas_2000.tif” file and then calculating the area of each category of the Legal Amazon protected areas. |
| + | </note> | ||
| \\ | \\ | ||
| \\ | \\ | ||
| - | **Go ahead!** Now, The intent is to calculate biomass and Carbon Dioxide content in Biomass in high priority conservation areas within protected areas. | + | ===For the second part of this lesson we calculate the biomass and Carbon Dioxide content within it in high priority conservation areas.=== |
| \\ | \\ | ||
| \\ | \\ | ||
| - | Initially, we must open all the files that will be used. Click on the Input/output tab from the library window and grab two Load Categorical Map functors and place it on the sketch. Double click each Load Categorical Map Functor and open the Legal Amazon Conservation Priority and protected areas map files. Also grab and place a Load Map and open the Legal Amazon Biomass map. You should have something like this: | + | * Initially, we must open all the files that will be used. On the Input/Output tab from the library window, grab two **Load Categorical Map** and place them on the sketch. Double click each **Load Categorical Map** and load the Legal Amazon Conservation Priority (''Guidebook Dinamica_4/Database/Priority_areas/priority_areas.tif'') and Protected Areas maps (''Guidebook Dinamica_4/Database/Protected_areas/protected_areas_2000.tif'').

| - | Now, grab a Calculate Map and place it on the sketch. Click in the hook tool to create three hook functors with Number Map inside the Calculate Map. Now assign a number to each Number Map (Suggestion: “1”, “2” and “3”, respectively). This is a number identifier for each map and will be represented within the equation box as i1, i2 and i3. | + | * Place a **Calculate Map** on the sketch.

| - | Now, you need save the result of biomass to a file. Grab a Save Table, place it on the sketch and connect the Calculate map to them. Open Save Map, browse to the folder preferred and write the name file (We suggest: biomass_high priority conservation_protected areas_map.tif).\\ \\ | + | * Now, you need save the result of biomass to a file. Place a **Save Map** on the sketch and connect **Calculate Map** to it. Open **Save Map**, browse to a suitable folder and write the file name (e.g. biomass_high priority conservation_protected areas_map.tif). |
