===== D.T1.1.1: Analysis of requirements for Smart Altitude web-based data publication and visualisation =====
 
=== Introduction ===

This document contains the preliminary requirements for the online WebGIS to be developed as part of WP1 and the Alpine Space / Interreg project Smart Altitude.

The requirements are split into two sections, 

  * the user requirements, or the user needs, describing what the WebGIS user wants to do with the system, and 
  * the functional requirements, describing distinct functions of the WebGIS which allow the user to perform the actions described in the user requirements

=== User Requirements ===

|UR-1 | |User needs to access an online tool to present and access the geospatial outputs of the Smart Altitude project |  
|UR-2 | |User needs to access an online mapping tool to access different data layers relevant to the project’s topic of low-carbon, high-impact energy production and consumption |  
| |UR-2.1 |User needs to access thematic data for wind energy potential and production | 
| |UR-2.2 |User needs to access thematic data for hydropower energy potential and production |
| |UR-2.3 |User needs to access thematic data for solar energy potential and production |
| |UR-2.4 |User needs to access thematic data for geothermal energy potential and production |
| |UR-2.5 |User needs to access thematic data for biomass energy potential and production |
|UR-3 | |User needs to access background data layers providing spatial context to the project’s thematic layers |
| |UR-3.1 |User needs to access background satellite imagery |
| |UR-3.2 |User needs to access background cartographic maps |
| |UR-3.3 |User needs to access background hill shade / relief maps |
| |UR-3.4 |Background layers need to be available for the whole alpine region |
|UR-4 | |User needs to access data generated and provided for the project’s living labs |
|UR-5 | |User needs to access data for the energy requirements of the project’s ski resorts |
|UR-6 |	|User needs to access data showing ski resort’s facilities and extent |
|UR-7 |	|User needs to access the user interface in the major languages existing in the alpine region |
|UR-8 |	|User needs to print hard copies and export PDF documents of map content |
|UR-9 |	|User needs access to a layer tree to |
| |UR-9.1 |Switch on/off and combine layers displayed on the map |
| |UR-9.2 |Change layer transparency |
| |UR-9.3 |Change layer drawing order |
|UR-10 | |User needs an online introduction / tutorial to the WebGIS |
|UR-11 | |User needs a calculation tool in order to combine and calculate parameters based on data available in the WebGIS |
|UR-12 | |User needs to identify features of displayed layers in order to access and display feature / metadata | 
|UR-13 | |User needs to access a layer legend and layer information / metadata |
|UR-14 | |User needs to download project specific data to their own desktop machine for further use |
|UR-15 | |User needs access to project layers in their own desktop GIS system |
|UR-16 | |User needs access to a full text search interface to find municipalities and other features as provided by the project data | 

=== Functional Requirements ===
|FR-1 |	|The WebGIS provides an online interface accessible on desktop computers with standard internet browsers: Microsoft Edge, Internet Explorer, Firefox, Chrome, Safari, not older than 2018 releases |
|FR-2 |	|The minimum screen resolution for an acceptable user experience shall be 1600 x 900 pixels |
|FR-3 |	|The minimum network bandwidth for an acceptable user experience shall be 5 Mbit/s |
|FR-4 |	|The WebGIS needs to provide a web mapping component, allowing |
| |FR-4.1 |Zooming and panning |
| |FR-4.2 |Cartographic representation / SRS to be EPSG:3857, Web Spherical Mercator Projection |
| |FR-4.3 |Display of a scale bar |
| |FR-4.4 |Display of a layer legend / styling |
| |FR-4.5 |Full screen map display |
| |FR-4.5 |Mouse cursor coordinate display in most common SRS, including Lat/Long (EPSG:4326), UTM, and Web Spherical Mercator (EPSG:3857) |
|FR-5 | |The WebGIS needs to provide public and private layer access in order to restrict public access to sensitive layers |
|FR-6 |	|Project layers to be exposed via OGC WxS web services |
