9.4 Interface between EMME/2 and GIS
9.4.1: Do you have utilities to exchange data between EMME/2 and a GIS database?
INRO has developed two utilities:
- EMARC, a set of procedures which can ease the data transfer process between EMME/2 and ARC/INFO (see Question 9.4.2).
- shp2ann, a utility to extract information from an ArcView shapefile containing POLYGONS or POLYLINES to produce an annotation file readable by EMME/2 (see Question 9.4.3).
INRO has developed EMARC, a set of procedures (AML macros, EMME/2 macros, AWK scripts) which enable data exchanges between EMME/2 and ARC/INFO and vice versa. The simple user interface of EMARC guides the user during the data exchange process, which is carried out by manipulating ASCII files (that is, EMARC does not access directly the binary data banks of EMME/2 or ARC/INFO). The conversion process implemented in EMARC follows the guidelines stated in the paper entitLED Development of a Data Exchange Protocol between EMME/2 and ARC/INFO by Robert Lussier and Jia Hao Wu, which can be found on the INRO Web site (arcinfo_EMME2.ppt). An EMME/2 coverage is built in ARC/INFO and is based on a one-to-one relationship with the EMME/2 network data. This relationship permits the development of an automatic process that performs the information exchange between the two software packages.
EMARC is available free of charge and can be downloaded from the INRO Web site. It is an unsupported utility. It is not part of any software licence agreement and there is no explicit or implied warranty nor any support from INRO. To obtain a copy, send an e-mail request to support@inro.c
