Avoiding the GIS-Model Disconnect: Identifying the Major Hurdles Associated with Hydraulic Model Creation and Updating from GIS
避免GIS模型断开:确定与从GIS创建和更新水力模型相关的主要障碍
This powerpoint presentation begins by providing a brief overview of geographic information systems (GIS) and model integration. The goal of this presentation was to
identify the hurdles which include the following: identify key stakeholders and decision makers; identify key goals and purposes; key ID requirements; identifying GIS elements to be included in the model; make all feature class subtypes translate to a single
model element type; connecting model elements together; model facilities require special considerations; track certain key model data in GIS; tracking deletions and changes in the GIS; and, flowchart of the model update process. GIS-To-Model update steps summary:
save an archive copy of latest model;
export GIS data to be modeled;
translate GIS to model elements;
remove deleted elements from model; import new GIS data to model;
perform QA and topology checks;
update key missing data for new or changed elements;
reassign model demands;
update scenario specific data;
validate model performance; and,
export model specific data back to the GIS. Includes figures.
