MOHID GIS Geographical Information System of the Water

MOHID GIS Geographical Information System of the Water Modeling System MOHID

Overview • What is MOHID GIS designed for / not designed for? • How does MOHID GIS interact with numerical tools • Organization of MOHID GIS – Projects, Views, Data Items • • • Zooming, Panning - online Saving Images - online Animating Display - online Legends - online Incorporated Tools - online

Introduction • What MOHID GIS is – A software to visualize spatial and temporal variable data used / produced by MOHID numerical programs – Interactive Tool collections to be used to produce input file for MOHID numerical programs • What MOHID GIS not is – A static program which never changes… – Software which authors are guilty for everything what’s go wrong in modeling tasks…

Organization of MOHID GIS • MOHID GIS is divided into: – Projects – Views (Child Windows) – Data Items • A View has: – List View – Display Area

Organization of MOHID GIS • Data Items can be: – – – Points – a set of XYZ points with optional name; Polygons – a set of polygons, without holes; Lines – a set of lines; Grids – a file which defines a grid, as used by the MOHID numerical programs; Grid Data – a file which defines a grid and the respective center cell values; Background Image – path to an image to be displayed and its geo-reference; Drainage Network - a file which defines a drainage network; River Cross Sections - a file which defines river cross sections; Time Series – a file which contains a time series; HDF 5 File – a file written in HDF 5; ESRI Shapefile – any valid ESRI Shapefile;

Organization of MOHID GIS • Adding Data Items… – Data Items -> Add… – Or

Organization of MOHID GIS • Data Items Properties… – Data Items -> Properties… – Or F 4 Data of Data Common Render Options Data Items (Point. Properties Size, Line(File Width, Name, etc) Envelope, Colorization)

Organization of MOHID GIS • Colorization of Data Items – Constant – Gradual – Classified • Limits are necessary even for Constant & Classified Color Scale!!! • Transparency apply to all types

Display can be 3 D
