Map 1 – HelvellynPlace name searchZoom out Map Content: only want to display water and land featuresMeasure shapeOverlays – add hillshadingSlide6

SearchCan pan/zoom to your location, or use SearchTab 1: place name/ road / postcode Tab 2: British National Grid reference or Lat/LongSlide7

Place name GazetteerPlace name search uses the OS 1: 50000 Scale GazetteerSame database that is used on the Landranger MapsSlide8

Map InformationDetails:Map productData licence – 2 possibilities:OS Licence (Digimap licence, educational use only)OS OpenData (wider use permitted, see OS Open Data website for full details)Date of creation by OSDefault print scaleGrid referencesSlide12

Map ContentOn this map, we are only displaying land and water featuresRemoved roads, boundaries, tourist features etcSlide13

Map ContentFeature selection available in 8 of Roam’s 14 viewsUnavailable when you are viewing a raster map - when unavailable, you will see the message ‘View has no layer selection’ TIP: check the basemaps for alternative maps where feature selection may be possibleSlide14

Raster v Vector map dataRaster map data is a matrix of cells (or pixels) in a grid:scanned maps, digital aerial photographs, satellite images, digital pictures. geo-referenced, geographic coordinates of the location added.useful as background for displaying other data.Vector map data stores data on individual map features e.g.Points such as train stations.Lines such as railway tracks and rivers.Polygons such as buildings or fields.We can view, query and analyse

vector map data.Slide15

MeasurementsAvailable under Map toolsMeasure distances or areasNot possible to save the measurements or print on your mapSlide16

Hillshading

Will be other overlays available in futureSlide17
