################################################################################ <# .SYNOPSIS Extracts geolocation data from an image file. .DESCRIPTION This function reads EXIF metadata from an image file to extract its latitude and longitude coordinates. It supports images that contain GPS metadata in their EXIF data. .PARAMETER ImagePath The full path to the image file to analyze. .EXAMPLE Get-ImageGeolocation -ImagePath "C:\Photos\vacation.jpg" .EXAMPLE "C:\Photos\vacation.jpg" | Get-ImageGeolocation #> function Get-ImageGeolocation { [CmdletBinding()] param ( ######################################################################## [Parameter( Mandatory = $true, Position = 0, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, HelpMessage = "Path to the image file to analyze" )] [ValidateNotNullOrEmpty()] [string]$ImagePath ######################################################################## ) begin { # check if image path exists if (-not (Test-Path $ImagePath)) { Write-Error "The specified image path '$ImagePath' does not exist." return } Write-Verbose "Processing image: $ImagePath" } process { try { # load the image file Write-Verbose "Loading image file" $image = [System.Drawing.Image]::FromFile($ImagePath) # get all property items $propertyItems = $image.PropertyItems # extract gps metadata properties Write-Verbose "Extracting GPS metadata" $latitudeRef = $propertyItems | Where-Object { $PSItem.Id -eq 0x0001 } $latitude = $propertyItems | Where-Object { $PSItem.Id -eq 0x0002 } $longitudeRef = $propertyItems | Where-Object { $PSItem.Id -eq 0x0003 } $longitude = $propertyItems | Where-Object { $PSItem.Id -eq 0x0004 } # check if gps data exists if ($latitude -and $longitude -and $latitudeRef -and $longitudeRef) { # calculate actual latitude and longitude values $lat = [BitConverter]::ToUInt32($latitude.Value, 0) / [BitConverter]::ToUInt32($latitude.Value, 4) $lon = [BitConverter]::ToUInt32($longitude.Value, 0) / [BitConverter]::ToUInt32($longitude.Value, 4) # adjust for south and west hemispheres if ($latitudeRef.Value -eq [byte][char]'S') { $lat = -$lat } if ($longitudeRef.Value -eq [byte][char]'W') { $lon = -$lon } Write-Verbose "GPS coordinates found: $lat, $lon" return @{ Latitude = $lat Longitude = $lon } } else { Write-Verbose "No GPS metadata found in image" return $null } } catch { Write-Error "Failed to process image: $_" } finally { if ($image) { $image.Dispose() } } } end { } } ################################################################################ |
