You can detail anything in several attempts and using multiple tools at once

  • if you are lucky to live close enough to area you want to see in detail, then survey it multiple times. Relax and don't rush for it using complex tools or demanding techniques or techniques that waste your time without results.
  • not every technique is reliable in every season and under every weather condition, you can use them in combination instead of picking just one
  • in areas with limited network connection you may prefer offline tools and editors, they may be more complex but it may be more reliable and faster
  • regardless of your techniques, your work can be explained in two steps:
    1. you need to know where things are (nodes and ways)
    2. you need to know what there is, (tags) namely the POIs (Points of Interest), street names and types. You can do these one after another, or both at the same time, but you can hardly do the what before the where.


Techniques (incomplete list)

For complete descriptions refer to Category:Data collection technique.

Use your memory

Because if you are familiar with your locality or just surveyed it, you don't need anything else. Tips:

  • Avoid old memories (even you live there for X0 years, world is constantly changing, your memories are outdated)
  • Avoid guessing
    • Mark estimations with note=* or fixme=*
    • Use special general tags like highway=road or building=yes or shop=yes instead of their specific variants
    • Temporarily mark objects with tag source=Bing if you didn't see them in every detail expect using from satellite imagery (Bing, for this example)
  • Describe hard parts or objects recently changed in the real world
    • simple but descriptive notes will help you and others during process
    • using good changeset comments so you don't have to rely on satellite imagery or anything else
  • Try to avoid big changes without recent knowledge of area


Use paper and pencil

  • Good drawing skills will help you to get fine details
  • Very cheap and independent of weather conditions (pencil will work from -60 °C to +40 °C), just make sure to protect paper (water and physical damage)

You can use video camera

Main article: Videomapping

It is simpler than other techniques with electronic equipment.

Using satellite navigation tracelogs

Usually you will get tracelogs with limited quality (~7 meters). Tips:

  • It may be useful when you draw roads for the first time in area of your interest
  • If will be less and less relevant during detalization process (since objects like footways and barriers are way less than precision of ~7 meters)
