Als je in een persoonlijke notitie van een cache geldige coördinaten hebt (bijv. N50 10.123 E010 34.876) zal c:geo automatisch een waypoint hiervan maken in het waypoint tabblad van deze cache.

Als je bijvoorbeeld deze persoonlijke notitie hebt gemaakt

zal c:geo automatisch dit waypoint hiervoor maken:

Latere coördinaten in je persoonlijke notitie zullen ook op dezelfde manier naar een waypoint worden overgedragen en zal de naam van het waypoint dienovereenkomstig worden genummerd.

Normaal gesproken definieert c: geo het waypoint-type voor coördinaten die in de persoonlijke notitie worden gevonden als Referentiepunt , maar u kunt trefwoorden in uw persoonlijke notitie gebruiken om het gebruik van een ander type waypoint af te dwingen.

Je plaatst eenvoudig een van de onderstaande sleutelwoorden voor het coördinaat:

Icoon	Waypoint type	Sleutelwoord in persoonlijke notitie
	Parkeerplaats	PARKING
	Te beantwoorden vraag	PUZZLE
	Multi-cache punt	STAGE
	Trailhead	TRAILHEAD
	Referentie punt	WAYPOINT
	Eindbestemmingn	FINAL

Ook zullen de namen van de waypointtypen in de taal waarin je c:geo gebruikt werken, maar aangezien c: geo in veel talen beschikbaar is, vermelden we hier alleen de Engelse trefwoorden.

In ons voorbeeld hebben we de volgende persoonlijke notitie gemaakt:

welke vervolgens automatisch in deze waypoints worden gemaakt:

Perhaps you noticed that waypoints from personal note were created with default names like e.g. Personal Note 2. If you want to perform more advanced waypoint operations from your personal notes you have to use an advanced waypoint syntax. With this you can:

• Modify properties of predefined waypoints (=waypoints which were predefined by the cache owner in the listing): coordinate and user note
• Create or modify waypoint type, name and user note in user-defined waypoints

To do this, use the following syntax in your personal note:

@[<prefix>]<name> (<waypointTypeId>) <coordinate> “<user note>”

The advanced format is recognized when it starts with a @ at the beginning of a new line. The following content is parsed:

• Waypoint name: everything between the @ and the coordinate is considered to be a part of the waypoint name, except when it is in parenthesis ()
• Prefix: If the @ is directly followed by square brackets [], then the content of these brackets is considered to be the prefix of the waypoint you want to edit
• User note: If the coordinate is immediately followed by “ (in same or next line), then everything between this ” and the next “ is considered to be part of the waypoint's user note (including line breaks). If the coordinate is not followed by ” but has additional content on same line, then this content is considered to be the waypoint's user note
• Waypoint type: same rules apply as discussed in previous sections.
• Coordinate: same rules apply as discussed in previous sections. Additionally there is a “special” coordinate tag (NO-COORD) which can be used to specify an empty coordinate (this is necessary in the very special case that one wants to modify the user note of a predefined waypoint which has no coordinate)
• Formula: same rules apply as discussed in previous sections. Additionally there is a “special” formula tag (F-PLAIN) which can be used to specify a formula in the plain-format. Cache-listings often contains already formulas in this format. You can specify any already known value for the variables separate by the |-symbol.
  The syntax of the formula must satisfy the criterias as described in Using Plain Coordinate Format.
  If you can determine the values for the variables only step by step, it is recommended to enable Prevent waypoints extraction until you have entered all variables in the personal note. Then the waypoint can be created with all values and the coordinates are calculated. (Note: the other formats are in progress)

The geocaches waypoint list is modified with this information as follows:

• If a prefix is parsed and a waypoint is found with the same prefix, then it is assumed that this waypoint should be modified. This is usually only used for predefined waypoints.
• If a waypoint is found with the same coordinate as the waypoint parsed, then it is assumed that this waypoint should be modified.
• Otherwise a new waypoint is created.

In case a waypoint is modified, the following rules apply:

• For predefined waypoints the only things that can be modified are the coordinate (if the cache owner defined it empty) and the user note.
• In existing waypoints, fields are only overridden when they are empty or filled with a default value (e.g. system-generated waypoint name)
• A formula in Plain-format will only be adopted if no formula or coordinate has been entered yet.

The following examples show different texts on the left and the waypoints created out of them on the right

Personal note text	produced waypoint
@ A good parking place N50 11.456 E010 35.345 park under the oak tree
@ (X) marks the spot N50 12.010 E010 33.783
@[S5]Station 5 (X) (NO-COORD) “We have to think about this later” Note: this example assumes that there is a predefined waypoint in the listing with prefix S5
@Final (F) (F-PLAIN) N48 AB.(C*D/2) E 9 (C-D).(A+B) |A=a+b|a=5| “Formula is calculated with the variables” Note: The formula is then transferred to the waypoint calculator (format Plain)
