The lat/lon grid can be displayed for maps of any scale and any projection.Provided you have entered your datums correctly OziExplorer will ensure that all positions are translated to the correct datum as required.ĭisplay the latitude/longitude grid or an alternate grid like UTM.
OZIEXPLORER MAPA HOW TO
OziExplorer can handle many different datums (over 100) and knows how to translate positions from one datum to another.Map Datums – over 100 map Datums supported, When you scan your own map or have a digital map which is not calibrated, you can use the built in calibration ability so the image can be used in OziExplorer. A map in OziExplorer is an image of a map which has been calibrated (geo-referenced) so OziExplorer can use any pixel position on the map to determine the true geographic position.(To create your own maps you need access to a scanner). OziExplorer has a map calibration option so you can geo-reference your scanned map (see below). When you cannot obtain the map you want from 3rd parties who have produced them in digital form as images, you can scan them yourself.You can use maps you scan yourself from paper charts. OZF – (Now superseded but still supported).The disadvantage of having the extra zoom images included in the file is of course the larger file size it creates. This provides zoom images below 100% which look almost as good as the original image. OZF2 – This format, which gives good compression, can be paged from disk, efficient for decompression of small image sections and also has separate images built into the format for various selectable zoom levels.Uses formats developed especially for use in OziExplorerCE (also can be used with OziExplorer). Maptech Superdisk Format (.RML) – Similar to the PCX format above but the images are compressed.Maptech PCX (.02.) – An older format produced by Maptech but still in use.Geo-referencing information can be read direct from the file. ECW – a format which gives good compression – developed by ER Mapper.If the SID image file is supplied with a (.SDW) file, OziExplorer can use it for geo-referencing. MrSID – a format which gives high compression.BSB format cannot be written by the user. BSB – a format developed specifically for mapping, gives good compression and the image can be paged from disk.The map images can be imported into OziExplorer to easily calibrate the image or can be manually calibrated using the OziExplorer load and calibrate option.) These formats may have geo-referencing information included in the image or as a separate file. (These proprietary formats have been licensed for use in OziExplorer where necessary. Uses Maps in many proprietary formats – BSB, ECW, MrSID JPG – Provides excellent compression but the fully uncompressed image must be loaded into RAM (non-paging), not recommended for use with large images.(8bit or 24bit color images are supported). This is the preferred "non-paging" format to use. PNG – This format gives good compression but the image must be decompressed and fully loaded into RAM (it cannot be paged from disk).(24bit Color TIFF files can be used but are fully loaded into RAM not paged from disk as the 8bit color TIFF images are). This format allows paging from disk so is efficient on memory usage. TIF – The TIF format has many different variations and compression schemes which can be used.The formats below can only be used in the registered version of OziExplorer. BMP – the only format supported in the shareware/demo version.Maps & Charts Uses Maps in many standard image formats - TIFF, BMP, JPG, PNG.
