Write down your motivatedanswers of the overall repetition exercises in this Word document. Explain your answers and use screen dumps, figures, tables or maps.

The maximum score is 100. The maximum score per exercise is given.

Provide the Word document with the following name: Roomnr_name1_name2.doc !!

Send this document at the end of the morning, before leaving the practical room via to Willy ten Haaf ( ).
Success!

Open a newArcMap document named ‘Repetition_M1-M9.mxd’ and save it in your Workspace directory. Change the name of theData Frame to ‘Repetition’. Set the projection of this Data Frame to ‘RD-New’ and the map units to ‘meters’. Add the datasets‘Landuse.shp’, ‘Roads.shp’and ‘elevheight.shp’ to this data frame and display the attribute C2 of dataset Landuse.shp.

  1. Select the old GIRS-building (Landuse_id = 13502) and answer the following questions.
  1. What is the feature-type of this building? (2)
  2. What’s the data structure of this building? (3)
    Explain your answer.
  3. Write down allattribute values of the old GIRS-building. (2)
  4. What is the coordinate system of this dataset? (3)
  5. What is the nearest road to the old GIRS-building and calculate the distance to the nearest road with ArcGIS?Show the resulting table and explain the steps you’ve taken. (5)
    (Hint: make use of a ‘spatial join’)
  6. What is theaverage distance from the old GIRS-building to the 5 nearest roads?Show the resulting table and explain the steps you have taken. (5)
    (Hint: make use of a ‘spatial join’)
  7. What is the majority slope aspect of the old GIRS-building?Show the resulting image and explain your answer based on a visual interpretationof this image and based on a moreexact calculation. (10)
  1. Continue working with Data Frame ‘Repetition’. Add dataset ‘soil_points.shp’ to the Data Frame and put the datasets ‘Landuse’, ‘soil_points’ and ‘Roads’ to the top of this Data Frame.
    Calculate the average clay-% of the soil profile points, which are located within the landuse features classified as ‘pasture’ (C2=5) and within a distance of 100 m to ‘Roads’?
    Explain your answer.

a.Write down this query according to the formal structure format of a SQL-query: (5)

Select:

From:

Where:

b.Write down this query step by step in the table below. Write down for every step the
datasetthat is queried, a short description of the step, the ArcGIS tool used for the step,
the query type (tabular or spatial) and a drawing or description of the result. (12)

Dataset / Step description / ArcGIS tool(s) / Query type / Result

c.Show the resulting table and write down the average clay %. (3)

3.The Centre for Geo-information has been very successful the last five years in educationand research and is growing so fast that the staff decided to move to a new building somewhere in the south of Wageningen. You, as GIS experts have been asked to map where the suitable areas in the southern part of Wageningen for building this new Centre for Geo-information’ are located.

The suitable locations for the new buildings are based on the following conditions:

  • To savecosts, the new building has to be built on a sandy soil; soils classified
    as ‘Holtpodzolgrond’ are suitable.
  • The new building has to be located within 100 meters from the nearest road.
  • Only locations with a slope angle between 10° and 25° are suitable.
  • Slopes facing South or South-East are suitable.
  • The total area for the new building, parking place, etc. has to be at least 1300 m2.

Continue working with Data Frame ‘Repetition’. Add dataset ‘lu_raster’to this Data Frame. Set the ‘Analysis Extent’ and ‘Analysis Mask’ to ‘lu_raster’.

NEW TOOL: at a certain point in the analysis you have to use a tool that has not been discussed in one of the previous modules: Region group. Consult ArcGIS Desktop Help system to learn more about this tool. Find out yourself at what point during the analysis you will have to use this tool.

  1. Give a systematic description (meta-data) of the datasets you want to use. (5)
  1. Design a complete data-action model / flowchart for this assignment
    including a legend and explanation of the different steps taken. (15)

Implement the designedprocess in ArcMap.

  1. Perform a final map (layout)of the suitable locations found in ArcMap and
    copy this map in this Word document. (15)
    (Hint: to export your layout/map go to File in the menu bar and select export map)
  2. How many locations are potentially suitable for the building of a new Centre for Geo-Information? What’s the total area of potentially suitable locations?Show the final table and explain your answer? (5)
    (Hint: to export a table open the (attribute) table, select options and select export data)
  3. What part of the potential locations(%) is covered by forests? First write down the data-action model or flowchart. Show both the map and the table. Explain your answer. (5)
  4. Is the old GIRS-building located on one of the potentially suitable locations you have found? If not, describe the reason(s) why this location is not potentially suitable. (5)
