1 INTRODUCTION The main objective of the GIS INTERFACE is to enable users with a basic knowledge of GIS to create thematic maps, which will help them to analyse and evaluate the results of the Crop Growth Monitoring System (CGMS) integrated with the Soil Geographical Database of Europe (SGDBE) and CORINE/Global Land Cover (CLC/GLC) data. The GIS INTERFACE is implemented under the ESRI® ArcMap

TM 9.x

environment. The GIS INTERFACE is programmed in Visual Basic for Application (VBA) using ArcObjects libraries. All commands and tools of ArcMap remain accessible. GIS INTERFACE is designed to work with the CGMS_07 database.

REQUIREMENTS OF THE GIS INTERFACE Basic requirements of the GIS INTERFACE are based on the Tender specifications Lot I – Task 2b: Development of GIS interface CGMS-SGDBE

The GIS interface should enable to produce the advanced thematic maps on user requirements based on data from integration of CGMS and SGDBE (Lot I – Task 2 Improvement of the soil model in CGMS)

Lot I – Task 3b: GIS interface for CGMS-CORINE advanced visualisation

The GIS interface should enable to produce the advanced thematic maps based on integration of CGMS output (level 1 and 2) with CLC classes (Lot I – Task 3 CORINE Land Cover implementation)

GIS INTERFACE modules and tools are accessible through the GIS INTERFACE toolbox.

The GIS INTERFACE manages the connection between the cartographical databases (represented by vector layers) and attributes data stored in the CGMS and SGDBE databases.

2.1 VECTOR DATA All vector data are administrated using the INSPIRE LAEA-ETRS89 co-ordinate system. The following vector layers are essential for the GIS INTERFACE:

NUTS0 / NUTS2 NUTS0 / NUTS2 are layers of topological polygons, which represent administrative boundaries. NUTS0 / NUTS2 are used for selection of geographical area and for visualization of results aggregated at the required administrative level.

GRID50 This topological polygon layer contains grid cells, each covering a rectangular area of 50 x 50km. Grids are used for selection of the geographical area and for visualisation of results aggregated within the grid.

SOIL MAP This topological polygon layer is the cartographical representation of the soil database. Each polygon of the soil map belongs to one Soil Mapping Unit (SMU). One SMU can consist of one or more polygons. An SMU is the base unit in the CGMS and SGDBE databases. SOIL vector is used for geographical representation of CGMS and SGDBE attributes, which are related to a SMU or a STU.

EMUPLUS This topological polygon layer is formed by the intersection of the SOIL, GRID50 and NUTS2 vector layers. EMUplus represents the smallest modelling unit in the CGMS database.

CLC/GLCMASK These polygon layers are derived from Corine Land Cover 2000 and Global Land Cover 2000 classes. GLC2000 is used for countries where CLC data doesn’t exist. Three kinds of masks are generated for arable land, two for pastures and one for rice. Masks are used to generate maps under the CLC & Soil Suitability module.

2.2 ATTRIBUTES DATA Data from the Crop Growth Monitoring System (CGMS) and the Soil Geographical Database of Europe (SGDBE) represent source attributes data for the GIS INTERFACE.

CGMS CGMS contains data from weather monitoring, crop monitoring and yield forecasting including yield and area statistics and the final synthesis. Data are stored in the ORACLE database.

SGDBE SGDBE data used in the GIS INTERFACE contain soil information for all Europe. In the SGDBE the smallest unit with soil nature information is a Soil Typological Unit (STU). The smallest cartographic unit is a Soil

Mapping Unit (SMU), which is represented in SOIL MAP. An STU contains information about distinct soil type and specifies the nature and properties of the soil. It is described only by its attributes. Data are stored in a dbf table. Each SMU is composed of at least one STU. The weight of an individual STU within an SMU is given as a percentage. The sum of percentages for STU units in each SMU is 100%.

3 RUNNING THE GIS INTERFACE For the successful running of the GIS INTERFACE the following must be met:

1. The GIS INTERFACE is running from the GIS_INTERFACE_ver*.mxd file. All modules are available through the GIS INTERFACE toolbar.

2. Initialization files GIS_INTERFACE_SETUP.ini and SCHEMA.ini must be available at the same directory as the GIS_INTERFACE_ver*.mxd file.

Figure 2 Checking Data Connection dialog box

Tools from this dialog box enable checking accessibility of vector data, connection to CGMS and SGDBE datasets, and activation of the CGMS-Webserver. Data for Weather and Crop indicators are obtained through the CGMS-Webserver. This application must be run before using the Weather or Crop Indicator modules. CGMS Webserver is the a database client which provides sending requests to Oracle CGMS database and saving the obtained datasets to the *.csv file see chapter 6.4, 6.5 and Figure 28

BASIC VECTOR LAYERS tool checks if all pivotal vector layers are connected. If all required layers are

connected, the user is informed via the message as in Figure 3 (a). If any vector layer is not available, the message shown in Figure 3 (b) indicates the missing one. It is possible to find and attach an appropriate vector layer to the project, see Figure 3 (c). In case one attaches a vector layer the mxd-file must be saved otherwise this has to be repeated during the next session.

6 THEMATIC MAPS The GIS INTERFACE contains the following modules for generating thematic maps: - Soil Suitability - Dominant STU - Crop Calendar - Weather Indicators - Crop Indicators - CLC & Soil Suitability

6.1 SOIL SUITABILITY MAPS The purpose of the Soil Suitability map is to present which crop can be included in the crop growth simulation for a given soil unit. CGMS contains the information related to the crop group and soil suitability stored in the SMU_SUITABILITY table. Data from this table are joined to the SOIL vector layer through an SMU_NO identifier. The SMU_SUITABILITY table contains fields SMU_NO (soil mapping unit number), CROPGROUP_NO (group which crop belongs to) and PERCENTAGE (percentage of soil mapping unit suitable for crop group). Before generating a Soil Suitability Map, the required Geographical Area must be selected.

Figure 10 Soil Suitability Map dialog box

Input parameters which are set up using the Soil Suitability Map dialog box (Figure 10): CROP GROUP THRESHOLD for suitability limit – default value is 25% AGGREGATION UNITS - default is SMU Generation of maps:

A Soil Suitability Map (SSM) is automatically generated in the following steps (see Figure 11- Figure 15):

Attribute data

1. Selecting all records from the SMU_SUITABILITY table which meet the selected CROP GROUP and THRESHOLD. A new SMU_SUIT_x.dbf table is created. (x = CROP GROUP number)

2. If AGGREGATION UNIT = NUTS2 or GRID, the SMU_SUIT_x table is joined with the EMUplus Selection layer. Attributes from the joined table are aggregated into required aggregation units. A new NUTS2sum.dbf table / GRIDsum.dbf table is created.

Vector data

3. Union of all features in the selected GA. A UNION.shp layer is created. 4. If the AGGREGATION UNIT NUTS2 or GRID is selected, all features from the NUTS2 / GRID layer,

which intersect the UNION layer, are selected. A new layer NUTS2 Selection / GRID Selection is created. All features from the NUTS2 Selection / GRID Selection are unioned. A new UNION.shp layer is created.

5. Selecting all features from the EMUplus layer which overlay the UNION.shp. A new layer “EMUplus Selection” is created. If AGGREGATION UNIT SMU is selected a new layer “SMU Selection” is created.

Joining Vector and Attributes data

6. If AGGREGATION UNIT NUTS2 or GRID is selected, the NUTS2sumTable / GRIDsumTable is joined with the EMUplus Selection vector layer. If AGGREGATION UNIT SMU is selected, the SMU_SUIT_x table is joined with the SMU Selection vector layer.

7. Visualization of results using color-ramp style (yellow = 5% - dark brown = 100%) Example of SSM – generated for parameters: CROP GROUP = CEREALS, THRESHOLD = 50%, AGGREGATION UNIT = GRID:

Output: The extent of the map is defined by the selected GA. Map can be exported to jpeg format by clicking the “Export to JPG” button in the Soil Suitability Maps dialog box – see Figure 10.

6.2 DOMINANT STU MAPS The purpose of Dominant STU maps is to create thematic maps for CGMS and SGDB attributes that specify the nature and properties of the soil. These attributes are related to a Soil Typological Unit (STU). Because the smallest cartographical representation in the soil database is SMU, the first step is to find the dominant STU (the STU with the highest percentage representation) for each SMU unit. Each SMU is composed of one or more Soil Typological Units. The total of the percentages for STU units in an SMU is 100%. The percentage of the dominant STU must be greater than or equal to the selected PURITY threshold value. Three types of maps can be generated within this module: Dominant Suitability for CROP GROUP, Dominant STU using attributes from CGMS and Dominant STU using attributes from SGDBE. Before generating a Dominant STU Map, the required Geographical Area must be selected.

Figure 16 Dominant STU Map dialog box

Input parameters which are set up using the Dominant STU Map dialog box (Figure 16): TYPE OF MAP - default is Dominant Suitability PURITY threshold for dominant STU - default is 5% CROP GROUP – for “Dominant Suitability - Crop Group” map STU attribute for “Dominant STU - CGMS” and “Dominant STU - SGDBE” map

DOMINANT SUITABILITY MAP FOR CROP GROUP Generating maps: Tables SUITABILITY (cropgroup_no;stu_no) and SOIL_ASSOCIATION_COMPOSITION (smu_no;stu_no;percentage) from CGMS are used for map creation. Dominant Suitability Map (DSM) is automatically generated in the following steps (see the Example DSM below): Attributes data:

1. Selecting all records from the SOIL_ASSOCIATION_COMPOSITION table which meet the selected PURITY threshold.

2. Summarizing all selected records (SMU_NO, Maximum.PERCENTAGE). A new SumTable.dbf is created.

3. Selecting all records from the SUITABILITY table which meet the selected CROP_GROUP. A new STU_SUIT_x table is created. (x = CROPGROUP number)

4. Joining the SOIL_ASSOCIATION_COMPOSITION table, the SumTable (join field = SMU_NO), and the STU_SUIT_x table (join field = STU_NO)

5. Selecting all records where CROPGROUP = x AND SOIL_ASSOCIATION_COMPOSITION.PERCENTAGE = SumTable.Maximum_PERCENTAGE.

6. Exporting selected records to an SAC_2.dbf table Vector data:

7. Union of all features in the selected GA. A new layer UNION.shp is created. 8. Selecting all features from the soil_etrs layer which overlay the UNION layer. A new layer SOIL

Selection is created. Joining Vector and Attributes data:

9. Joining table SAC_2 with the SOIL Selection layer. (join field = SMU_NO) 10. Visualization of results using color-ramp style (yellow = 5% - brown = 100%)

6.6 CLC & SOIL SUITABILITY MAPS The purpose of the CLC & Soil Suitability maps is to present which crops can be included in the crop growth simulation for a given soil unit with integration to the CLC/GLC database. Generation of a CLC & Soil Suitability map is similar to the generation of a Soil Suitability Map – Chapter 6.1.

Figure 31 CLC & Soil Suitability dialog box

Input parameters which are set up using the CLC & Soil Suitability dialog box (Figure 31): CROP/CROP GROUP THRESHOLD for suitability – default value is 25% CLC MASK

CLC MASK The CLC mask is primarily derived from CLC 2000 classes, GLC 2000 data are used for countries where a CLC 2000 dataset doesn’t exist (e.g. TR, NO, CH, ...). The CLC mask is created by vectorizing appropriate CLC/GLC classes which were originally saved in grid format. To reduce the size of vector data, the smooth function was applied - Figure 32.

Table 3 Applicability of CLC masks for particular crops

CLC masks are used to improve Soil Suitability maps based solely on SOIL MAP – chapter 2.1 and 6.1. The combination of CLC MASK with SOIL MAP enables more precise specification of regions suitable for a specific crop. The following vector layers (CLC masks) are created for the purpose of generating thematic maps under the CLC & Soil Suitability module: CLC_ARAB1 (clip of SOIL MAP with ARAB1 CLC mask) CLC_ARAB2 (clip of SOIL MAP with ARAB2 CLC mask) CLC_ARAB3 (clip of SOIL MAP with ARAB3 CLC mask) CLC_PAST1 (clip of SOIL MAP with PAST1 CLC mask) CLC_PAST2 (clip of SOIL MAP with PAST2 CLC mask) CLC_RICE (clip of SOIL MAP with RICE CLC mask) Generating of maps: A CLC & Soil Suitability Map is generated in the following steps

Attribute data

1. Selecting all records from the SMU_SUITABILITY table which meet the criteria for CROP GROUP and THRESHOLD. A new SMU_SUIT_x.dbf table is created. (x = CROP GROUP number)

Vector data

2. Union of all features in the selected GA. A UNION.shp layer is created 3. Clipping the ”selected CLCmask layer” with the UNION layer

Joining Vector and Attributes data

4. Joining this SMU_SUIT_x table to the clipped layer (join field = SMU_NO). 5. Visualization of results using color-ramp style (yellow = 5% - dark brown = 100%)
