1 Extracting RESULTs Information from the Land & Resource Data Warehouse (LRDW) The following instructions will illustrate how to extract inventory Results information from the Land & Resource data Warehouse (LRDW). The LRDW is a spatial data repository stored in an Oracle database and accessed through ESRI s SDE spatial data management and processing system. Overview Veg_Comp_Poly (Vegetation composite polygon spatial) To link veg_comp_poly (spatial) and veg_comp_layer (data set), use the feature_id attributes. Feature_id is a unique number to every record. The Veg_comp_poly composite table, it will contain attributes found in the following tables: polygon table land cover component table non tree table non vegetated table label table results linkage (refer below for more information) history linkage district code (attribute) Results Linkage To view silvicultural information, join the rslt_opening_poly table using the attribute opening_id to veg_comp_poly table opening_id. Join the rslt_forest_cover table with the same attribute opening_id to rslt_opening_poly table The link field (results opening_id) create one to many joins to the disturbance (burn, insect, logging, etc.) and management activities reported to the MoFR in RESUTLS.

6 C. Select specific TSA boundary by attribute 1. Click Selection on the tool bar and Select by Attributes 2. On the Select by Attribute form, make sure that whse_admin_boundaries.fadm_tsa is the selected layer, and double click TSA_Number in the Fields listbox. Notice that the field name gets added to the large text box at the bottom of the form, then click on the = (equal sign) operator. 3. Double-click on the desired value (in this example 15 is the code for Lillooet TSA). You have just built the expression portion of a SQL statement by choosing a database field (org_unit_no), an operator (=) and a value (15). When ready, click the Apply button. 4. If you want to select more than 1 value (in this example, select 2 tsa area), after the first expression, click on And and enter your second expression as stated in #3 (for example, Extracting Inventory Results Information from the Land & Resource Data Warehouse (LRDW 6

7 select 15 for Lillooet TSA and 20 for Morice TSA, the expression would be the following: TSA_number=15 and TSA number=20). 5. Convert the selected features into a map layer by right-clicking the feature layer name and choosing Selection Create Layer from Selected Features. Notice that a new layer gets added to the Table of Contents using the original feature layer name with the word selection appended to it, to differentiate it from original feature layer. 6. Detach the original provincial FADM_TSA layer from your Table of Contents by right-clicking on the feature layer name and choosing Remove.

Notice that your personal geodatabase now contains 2 feature classes. Extracting Inventory Results Information from the Land & Resource Data Warehouse (LRDW 16

17 8. Repeat the above for rslts_opening_poly. After you ve repeated the above, your table of content should look like the image below. The personal geodatabase should include the following: a. lillooet_tsa_boundary (Lillooet TSA boundary) b. lillooet_veg_comp_poly (vri composite polygons) c. lillooet_rslt_opening_poly (results openings polygons) Extracting Results Information from the Land & Resource Data Warehouse (LRDW) 17

18 G. Join rank 1 polygon attributes 1. To create a join between the LRDW Lillooet TSA vegetation composite polygon and the LRDW vegetation attributes (rank 1 layer), right-click on the feature layer name whse_forest_vegetation.veg_comp_poly selection, and choose Joins and Relates Join 2. In the Join Data form, select the feature layer whse_forest_vegetation.veg_comp_lyr_r1 from the choose the table to join to this layer combo-box. Note: veg_comp_lyr_r1 is an Oracle view of some vegetation attribute records based on a ranking of importance of the forest layers. R1 means that the database record for the layer where Rank = 1 is included in the database view: any other records where Rank <> (not equal to) 1 are not included in this database view. This creates a view with a one-to-one relationship between a vegetation polygon and a single forest layer attribute record (excluding any additional layer records when they exist for multilayered forest stands).

Click and hold on the Lillooet_veg_comp feature layer name and drag it down so that it is below the Lillooet_tsa_boundary feature layer name, then release the mouse button Extracting Results Information from the Land & Resource Data Warehouse (LRDW) 25

26 12. The Table of Contents lists feature layers in a hierarchy: those layers higher up in the TOC list get displayed on top of the layers below them in the list. 13. Notice that the Lillooet_TSA_boundary layer now masks out that portion of the Lillooet_veg_comp layer that is directly below it. 14. The reason that some polygons in the Lillooet_veg_comp layer extend beyond the Lillooet_tsa_boundary boundary is that we did a Select by Location intersect between the two LRDW layers, which includes all polygons that are all or partially intersecting between both layers. 15. Because the LRDW is made up of seamless layers, the vegetation polygons do not necessarily stop at TSA boundaries (a large alpine polygon that is continuous on both sides of a height of land may extend beyond a tsa boundary). The next step is to clip the vegetation polygons to the tsa boundary. Extracting Inventory Results Information from the Land & Resource Data Warehouse (LRDW 26
