大きなMisclose距離を伴う記録データの処理

Question

<\/HEAD>古い地図のいくつかをparcel fabricにトラバースしようとしたところ、記録された方位と距離がある区画が、指定された許容誤差（0.3281）内で閉じておらず、この大きなmiscloseによりトラバース後に面積が記載されていない地図がいくつか見つかりました。<\/P> <\/P> 以下の例では、tax parcels上に区画名、記載された面積、およびmisclose距離が表示されています。ご覧の通り、面積が記載されておらず、大きなmisclose距離を持つtax parcelsがいくつかあります。（参考として1922年の地図も添付しました）。<\/P> <\/P> 質問ですが、これらの区画は閉じていないことを承知の上でfabric内に保持することは適切でしょうか？この種のデータはどのように管理していますか？このような状況での情報をいただけると大変ありがたいです。<\/P> <\/P> <\/P> <\/P> <\/P> <\/P> Walid<\/P><\/BODY><\/HTML>

And keep in mind that the data model for the parcel fabric allows for record bearings and distances (and misclosure residuals) to stay with the parcel even after it has been joined to the adjacent parcels. As long as you are sure that your basis of bearings, point of commencement, and point of beginning are correct and the adjacent parcels are fitted to the rest of your fabric, those errors will still be part of the parcel's metadata.

I'm not a surveyor but having worked with / for them for over 20 years there are a couple approaches you could take. According to Wattles ("Writing Legal Descriptions", 1979), monuments cited or existing physically hold over everything. So, if the record data had "calls" to a right-of-way or any other cited / recorded land corner or line will hold over distance and direction.

Next is distance. Distance is weighted over bearings particularly because of objectivity in portions of the basis-of-bearing or because of contrasting adjoining descriptions disagree. So, if any of your adjoining parcels are cited within one of the non-closing others, and one of them is closing within a reasonable error, then hold that parcel as described to test better alignment or fit.

This is one of the primary elements associated with raw record data requiring cogo to prepare parcel fabric data. It won't always be correct. In your traverse editor there are options to adjust a polygon and the results can be evaluated to see if they'll still agree with the rest of your fabric. In reality, the parcel is closed by 4 bounding monuments of some type. The misclosure is due to insufficient calculations or a scrivener's error
