#Define parcel how to

In order to fully understand how to override a feature’s representation it will be helpful to know how I set up my layer’s symbology. To do that, an override for these features’ representations is needed. For example, the features shown to the right will not align if the hooks are centered on the parcel lines. The issue here is how to get the hooks to align so they are exactly opposed. Single hook on opposing parcel lines that are offset: In this case the Decorations marker placement option for a representation marker line will work well. Single hook at the end of a parcel line: Since parcel line features may be broken based on how their dimensions are described, ia hook may need to be shown at the beginning of a parcel line.

The only difference for the first case is that one of the marker line layers is not present. The representation rule (below to the right) is set for the second case, i.e., there are two marker lines. Single hook centered on a parcel line: The images below show two scenarios for this situation: one where the hooks are on different lines and the other with the hooks on the same parcel line. A few are fairly simple to follow, so I’ll describe them first: Even if you don’t have that attribute, it is pretty easy to use the Editor with these representation rules to add hooks for your parcel lines.Īs I mentioned above, I found several scenarios that required different representation symbology options. In terms of your data, the only requirement is that you are using a geodatabase, which allows you to use representations, and that you have an attribute that describes whether a parcel hook is located on a line, and if so, which side of the line. Notice that the hook symbol is inserted at the X in the Marker Editor this allows the hook to be rotated around that point. The latter option will permit display of parcel hooks in a different layer (that still refers to your parcel lines data) along with other parcel line layers that may, already be annotated or have dimensions. We provided two options, one where there were parcel lines included in the representation rule, and another without lines, which will just draw the marker line in the representation rule, i.e., only the hooks. We created a few of these markers and some representation rule line symbols and saved them in a style called RepParcelHooks.

To the right is an example what the hook would look like as a representation marker symbol. However, after acquiring some parcel data that included parcel hooks (thanks to Greene County, NC) and seeing the circumstances where parcel hooks (they’re also called land hooks or parcel ties) are placed on maps, I learned there are are several scenarios that need to be handled.įirst, the basic form of the symbol is a hook, rather than a tie, which is what the symbol in upper left image initially lead me to understand. Sure, just use the line decoration option on a marker line representation. Last week we received a good question on Ask a Cartographer: is there a way to create parcel hooks with ArcGIS 9.2? After first discovering what parcel hooks were and finding an example of a typical case (shown at left), the answer seemed like a ‘no-brainer’.
