Coverage table, in “T_VALORES” model, is a table with all the information about covers and SIOSE attributes linked to each geometry of “T_POLIGONOS”. Both tables are related by ID_POLYGON field.
“T_VALORES” table contains: area or percentage that a cover occupy into the polygon, relation between all polygon covers, associated attributes, etc.
There are a register per cover, so the same polygon will be represented as register as covers contains.
“T_VALORES” fields are described in the table below:
Campo |
Comments |
ID1 / OBJECTID |
primary key. it allows to the entire table row will be unique identified. |
ID_POLYGON |
it is the Universal Unique identifier (UUID) of polygons, URN namespace. it is related with ID_POLYGON field of “T_POLIGONOS” table. |
ID_COBERTURAS |
cover identifier of each polygon (see table 4). |
ID_ANCESTROS |
it is a field that stores the id of the coverage/coverage depending on other in turn, separated by commas. |
INTER_ID |
it’s a unique sequential identifier, it shows the order in which coverage appear into the polygon. |
INTER_ANCESTROS |
it’s a field keeping the relationship between the actual cover and the REST of polygon covers. it points out the INTER_ID of the covers that it depends on, separates by commas. |
ATRIBUTOS |
It’s an identifier of attributes. It characterises that land cover, separated by commas (See table 6). |
SUPERF_HA |
this is the area occupy by covers within the polygon with a precision of 4 decimals places. the surface value has been obtained over the original PROYECTION in which they were digitalized, that is utm projection in their autonomous communities zone. |
SUPERF_POR |
it’s the area percentage occupied by the coverage within the polygon. Digit with 2 decimal places as maximum, but it can vary from 0 to 100. |
