Building a PaleoGIS model without a PaleoGIS license, access to MS Access and being in Windows is close to impossible. There are ways to programatically do this but almost exclusively this is limited to the settings above. Some days of researching the webs didn't yield anything useful (e.g. using Python to write the database table). The used
*.mdb format makes it very hard to reverse-engineer, the inability of ArcGIS to rename the
OBJECTID field in the plate rotation table is another one.
Here's my take on what I think is the most robust way to generate a working PaleoGIS model without actually having access to PaleoGIS. It leaves the last step of model building (importing the rotation file) to the PaleoGIS user with a valid license:
Feature Class (single)or
Feature Class (multiple)depending on your input.
T_Model_Settings(required PaleoGIS model settings table),
PLATENAM(optional, referenced by the
NUMBER_NAME_MAPPINGparameter in the settings table).
DATATYPE(this table is required by PaleoGIS and is referenced by the
DATATYPE_NAME_MAPPINGparameter), as well as
T_Model_Settingsinto an ArcMap window, and choosing 'Edit', modify the following parameters in the
T_Model_Settingsin a way that the variables point to the correct feature classes or tables:
TIMESCALE_PREFERRED: Value should be set to the name of the timescale table you've copied into your database.
DISPLAY_LAYER_[1-9]: Value should be set to the feature class that should be displayed when the model is loaded. Increment the number at the end of the name string for any other added feature. Note that you need to use the following notation if you have simple, unstyled feature classes:
$PGD$|<Your feature class name>, if you have styled layers files, the syntax becomes:
$PGD$|DATABASE_LAYERS\<Your feature class name>.
DATATYPE_NAME_MAPPING: This value points to the
DATATYPEtable which is required to be present.
TIMESCALE_SOURCE: Name of the timescale table.
DISAPPEARS_COLUMN_1to the correct names of the corresponding columns in your feature class files. Following the formal GPlates Standard Naming scheme, the column names should be
MODEL_REFPLATE_COLUMNunchanged as the PaleoDataConverter output will automatically use the default PaleoGIS naming scheme for these columns
Once the database is complete and the name-attribute mapping in the
T_MODEL_SETTINGS table is correct, pass the database on to your friendly plate modeler with a PaleoGIS license. The steps to complete the assembly of the PaleoGIS database are then simply to:
Register Model, then click on the
…Button next to
Model Path. The settings table should be automagically be registered, as the model name (
CITATIONvalue in the
T_MODEL_SETTINGStable). Once done, click
OKto load the model (with the tickbox for
Load model after registeringchecked).
