Spreadsheet - Maps

For certain spreadsheets you can display the content in a map. The content will be displayed with the GIS-Editor like in the example below.

To set the symbols etc. representing the values, click on the button. A window as shown below will open, where you can set the parameters for the map. 

Transparency     

For the creation of heat maps, the transparency of the symbols displayed in the map can be set to a value below 255 (= no transparency).

 

Symbols

The symbols can be linked to the value within the database. A typical example would be the status of a plant, e.g. endagered, rare etc. stored as an analysis. Choose the Table where the values should be taken from. Now you can choose the column within the table. The different values will be listed and you can attribute a symbol together with the size to every listed value. In the image below, the symbols are linked to the values of a column named Last Nr for a certain analysis. 

The tables in the drop down list (see above) correspond to the content and definitions in the spreadsheets. Accordingly the values the symbols are linked to are restricted to the current content of the spreadsheet. As an alternative and in preparation for data containing other values to get the whole range of possible values you can select the source for the values from the whole database. Click on the button to select the source table. The programm will try to find the relevant data an make a proposal as shown in the image below.

If the proposal does not fit, set the source manually: In the window that will open as shown below, choose the source table for the values and click OK. (The table names in this list correspond to those in the database) 

This will open the source table as shown below. Here choose the column for a filter, e.g. AnalysisID, select the type of comparision and enter the restriction value. Now you can click on the button to restrict the values. In the example below the values were restricted to the analysis with the ID = 2. Finally select the column containing the values you need (AnalysisResult in the example below) and click OK (see below). 

Now all values from the source are listed, not only those contained in the data form the spreadsheet (see below). The button will change to and will now remove the source, to return to the values contained in the spreadsheet. If certain values should not appear in the map, choose as symbol. 

If the list does not contain a missing value, a separate control will appear at the end of the list, where you can set the symbol for missing values (see below).

The size of the symbols can be set either for every symbol or for all symbols with the button Set this size for all symbols. Another option is to link the size of the symbols to a numeric value within the data (see below). Choose the table and the column within this table containing the numeric value.

 

Colors

The colors can be linked to numeric values within the database. Select the table and the column where the values should be taken from. Now click on the button to add colors and the restrictions linked to the colors as shown below. 

 

Legend

With a click on the button, you can open a window listing all symbols and colors with their attributed values (see below). In the spreadsheet window, click on the button underneath the button to open the legend. 

 

Evaluation

There are 3 types of maps available:

Map for WGS84 geography of organisms

For this map type you have to set the table and the column containing the WGS84 geography, i.e. a content like POINT(45 ... )  for the organism as shown below. Every entry will be shown in the map with its exact geography.

 

Map with WGS84 coordinates

For this map type you have to set the table and the column containing the WGS84 geography, i.e. a content like POINT(45 ... ) for the collection event as shown below. Every entry will be shown in the map with the symbol placed in the center of its geography.

 

Map for objects aggregated according to TK25 quadrants

Filter table / Column: For this map type all objects within a TK25 quadrant will be aggregated to one value. For the filter according to which the aggreagation is performed, you have to select the table and the column containing the combination of the TK25 identifier and the quadrant (see below).

Gazetteer for retrieval of TK25 coordinates. The coordinates for the symbols will be obtained from a gazetteer module. Please select the source as shown in the example below.

Sequence of the symbols as shown in the map: The sequence of the symbols resp. the states linked to these symbols can be set here. Use the button to add an entry at the end of the list and the button to clear the whole list. To remove a single entry from the list, just click the entry you want to remove.  

With the option Keep last valid symbol if later data are missing you can keep the last valid symbol if in the later evaluated data the correspondig values are missing.  

 

Map

To display your data in a predefined map you can set this map with a click on the button as shown below.

With the option Show details in map the tooltip in the map will display the details of the data as selected in the spreadsheet (see below). The widths in the tooltip roughly corresponds to those set in the spreadsheet. 

 

Maps for organism geography , WGS84 coordinates of the collection event and TK25

After the parameters for the map are set you can choose among 3 types of maps:

Map with WGS84 geography of the organisms

This map will show the geography of the organisms.

 

Map with WGS84 coordinates of the collection event

This map will show all entries with a WGS84 geography.

 

Map for objects aggregated according to TK25 quadrants

This map will aggregate all entries according to the TK25 quadrants as shown below.

To select the data that should be edited either use the frame (as described in GIS: Save samples  and  GIS: Settings ) or select resp. deselect single data with the mouse. Click OK to close the map and return to the spreadsheet containing only the data selected in the map for further editing. For the TK25 map the filter will be set for the TK25/Quadrant column while for the WGS84 map the filter will be set for the column IdentificationUnitID corresponding to organisms shown in the map. The column IdentificationUnitID will be shown in the spreadsheet if you use the later filter.

As only one symbol and color can  be shown for every quadrant, a certain routine is used for the determination.

Color: For the color sortable values must be provided, e.g. the year or a period. The sorting will be according to the values were the highest value (e.g. the last year or period as determined by the user, see above) is preferred.

Symbol: For the symbol the sorting is determined by the user (see above).

The default routine for the determination:

  • Reduce the values for the quadrant to the first digit e.g. 2413 will be reduced to 2
  • Test every data row in the table that corresponds to the filter value (e.g. TK25 + Quadrant as determined by the user, see above).
    • The geography can not be determined - ignore this row. (The geography is determided via a gazetteer, see above)
    • The value for the color is missing - ignore this row.
    • The value for the color found in the data row is higher than the value found so far
      • Use this row to determine the color
    • The value for the color in the data row is higher than the color value associated with the symbol found so far
      • Use this row to determine the symbol
        • The row contains NO value for the symbol and the option "Keep last valid symbol if later data are missing" is NOT selected
          • Use the symbol for missing values (determined by the user, see above)
    • The value for the color in the data row is equal to the color value associated with the symbol found so far
      • The value for the symbol in the row is above the value found so far
        • Use this row to determine the symbol
  • No value for a symbol is found
    • Use the symbol for missing values (determined by the user, see above)
