The Object Of The Acquisition Is A Browser-Based Geospatial Application, Which Would Be Acquired As A Saas (Software As A Service) Service. The Application Would Be Used In Various Water Management Tasks, E.G. In Catchment Area Planning, Permit And Control Tasks, Water Management, Including Stormwater And Flood Risk Management, As Well As Watercourse Regulation And Dam Safety. In Addition, The Application Would Be Used In Water Management And Area Use Planning As Well As In Nature Conservation Tasks. The Key Functionalities Of The Application Are The Delineation Of The Catchment Area Above Any Point And The Presentation Of Flow Paths According To The Size Of The Selected Catchment Area, As Well As The Examination Of The Various Characteristics Of The Catchment Area (E.G. Surface Areas) In Terms Of, For Example, Land Cover, Land Use, Soil Or Slope. The Application Should Be Quick And Simple To Use. The Purpose Is For The User To Be Able To Perform The Most Common Checks Related To Water Management Quickly, In A Few Minutes, Without Separate Geographic Data Knowledge Or Heavy Analyses. The Application Should Be Especially Suitable For Quick Evaluations Of First-Stage Alternatives And General Design-Level Reviews. If Necessary, More Detailed Analyzes Can Be Done In Separate Geospatial And Flow Modeling Software. Use Cases Of The Application Include, For Example, Processing Of Drainage And Dredging Notices, Wetland Planning, Restoration Of Marshes, And Small Water Restoration Projects (Stream Restoration). In Syke, The Application Would Also Be Used In The Flood Center Service, Which Supports Regional Authorities Such As Vital Energy Centers In The Event Of A Flood Threat And In A Flood Situation. The Application Should Enable Quick Analyzes Of The Rise Of The Water Level, At Least In The Case Of Deep Water (E.G. Lakes And Sea Areas) As Well As The Places Where Runoff Accumulates On The Ground (Pressures, Including Calculation Of Volumes), Which May Arise As A Result Of, For Example, Heavy Rains Or Melting Snow. The Analyzes Should Be Able To Use Up-To-Date Open Height Information From The Land Surveying Institute (Mml) (At Least Height Model 2 M). Mml Maps And Orthoimages Should Be Used In The Background. In Addition, It Would Be Good For The Application To Also Offer Other Open Spatial Data Materials Useful For The Aforementioned Uses, E.G. Through Interfaces. The Application Should Have The Possibility To Modify The Elevation Model, For Example To Add Missing Road Culverts, And To Plan Various Measures At The General Planning Level, Such As Wetlands, Temporary Flood Embankments And Flood Detention Areas. The Application Should Support Sso (Single Sign-On) Login. The User Should Be Able To Create Workspaces In The Application That Can Be Shared With Other Users, Bring Their Own Materials Into The Application For Analysis (E.G. Elevation Models, Terrain Modifications Or Drums) And Download The Aforementioned Spatial Data Materials And Results From The Application To Their Own Workstation For Possible Further Analysis (Import And Export). Varies In The Longitudinal Direction Of The Riverbed), You Consider The Time Dimension (E.G. The Progression Of The Flood Caused By Heavy Rain And The Accumulation Of Water In Relation To Time) And Would Also Provide Simple Dimensioning Tools For Watershed Planning (E.G. Determining The Dimensioning Drainage/Flow Of A Wetland).
