(1) Question: PCArcInfo to ArcGIS, that's a big jump. Does your plan for this project to upgrade software and data include other interests like workflow enhancements and integraton with CAMA/Tax systems?

Response: NY uses the Real Property System for their CAMA (http://www.orps.state.ny.us/rps/index.cfm). Our current data, once converted to shapefiles, can be linked to the Access database backend for that software. We’re expecting that we would continue to follow that model. By virtue of the conversion process itself, we’re expecting a number of workflow enhancements to the process. We do use ArcGIS in the Real Property office for some of the work we do; at this point we’re trying to get all of the data caught up so we can use the one system and reduce our dependence on archaic software.


(2) Question: How many parcels are in the county?

Response: approximately 38,000

(3) Question: You mentioned converting to Shapefiles, are you planning to manage your data as Shapefiles or look to use one of the types of Geodatabases when migrating to the current version of ArcGIS?

Response: We currently convert our PC ArcINFO coverages to shapefiles for distribution to various agencies and users. We will continue to distribute data in shapefile format, however we would like to maintain the data in a geodatabase as the shapefiles are limited in functionality.


(4) Question: You also mention that you are trying to get caught up? Do you have a maintenance backlog that your are catching up?

Response: We do not have a maintenance backlog at this time. We are hoping to catch up in terms of the technology so that we have greater interoperability with our user base and other departments within the county and state offices.


(5) Question: Also, what types of maps/data are you currently using ArcGIS for in the office?


Response: We currently use ArcGIS for creating custom maps for the public and goverment agencies. I also use ArcGIS to perform sales analyses and to assist the planning deparment in understanding our data. ArcGIS is mainly a visuallization tool for the department at this time. We would like to use it exclusively for data maintenance, in addition to these other purposes.


(6) Question: Item 5 of the Requirements requires the vendor to provide a method for linking the geodatabase to the Real Property System Online (RPS) data. Does this refer to the “ORPS Online” application, or does Madison County have their RPS data available on a central server, where it could be accessed?

Response: Madison County has the data on a central server where it can be accessed by all county departments.


(7) Question: When we extracted the data, we discovered that about half of the coverages were corrupt and not readable. Could we get another delivery of clean data? I can provide our FTP upload information to speed up this process.


Response: There is an ArcGIS help note with the following: "If you use WinZip to extract a zipped .e00 file, it can potentially corrupt the data. A configuration setting in the WinZip program—TAR file smart CR/LF conversion—needs to be unchecked. To learn more, see article 17135 on the ESRI Support site."
If the extration worked and the layers can be seen with ArcCatalog, there are a few layers that will not draw if added to ArcMap using the default add process at the top layer of the coverage. These are primarily annotation layers (ones with an ls append for example). You will have to add them to your project individually by selecting the appropriate layers.
I can upload a copy of the files to an ftp site if requested.


(8) Question: Can we get the most recent imagery for the area to complete the pilot project? Again, I can provide our FTP upload information to speed up this process.


Response: Yes, we can make the most recent NYS Orthophotos available for this area - please send FTP permissions via the email in the RFP.


(9) Question: We have several questions regarding the “white cards” that make up the property card catalog.

1. What is approximate number of cards that need to be captured?

2. Are the cards double sided? If they are single sided is all of the information on the front side?

3. Are any cards stapled together or are any items stapled to the cards?

a If any items are attached to the cards, is it to be captured?

4. The cards are to be indexed with the tax ID number, are they in tax ID number order?

5. Can we get a representative sample of the “white cards”?



Response: 1. About 40,000, we think. We aren't sure of the exact count because of merges and continuation cards.

2. There are very few cards with information on the back, unfortunately there are a few and we'd like to capture that information.

3. Yes, cards that have been merged or ones where we have run out of space have been stapled together. There are maybe a handful of cards with a sticky note attached to them - this does not need to be captured. Cards that are stapled together should be scanned as a single unit as they now represent one tax unit.

4. On a whole, the cards are filed in tax ID order within a single city or town. The full county is not filed numerically, beginning to end. There are cards in the files that are not active parcels - they show us properties that may have been deleted. The tax id is listed at the top of every card. There may also be cards that have been mifiled in a different section or even municiplaity.

5. We can't provide hard copy examples. But I was able to scan examples of a card in decent shape (Oneida 38.45-1-1.17), a slightly damaged card (Oneida 38.48-1-70), a merge replacement card (Oneida 38.45-1-7), a continued card which is two stapled together (Oneida 38.53-1-29) and a series of merged parcels which are also stapled together (Hamilton 168.7-1-1.11).

NOTE: Some of the white cards are in poor shape. They are frayed at the edges. All cards will have to be returned once the project is completed so we can permanently archive the cards.


(10) Question: Could you confirm which version of RPS the County is using?

Response: RPS Version 4 Build 2009.1130


(11) Question: Can you send an image of the seal of Madison Co for the lower left corner of your tax map?

Response: Yes, the image is here.


(12) Question: We are coming across a significant amount of redundant data in the files you provided. Could you confirm the types of features or annotation included in the various file names and also include any differences between them: c04900 (no ending)
cr
gl
ls
lt
pr
rd
sl
ss
zz

Response: The file with no ending is the main parcel layer which includes the centroid of the parcel (x_coord and y_coord), the tax id (curprikey) and whether the polygon is the main parcel in the tax unit or a continuation due to a barrier of some type (centroid). The other postfixes are as follows:
cr = water layer (creeks).
gl = great lot lines, from large unit land sales during westward expansion.
ls = historical annotation layer. Used as a reference, not displayed on the tax maps.
lt = annotation layer.
pr = historical parcel layer information. Generally what the layer looked like at the time of initial tax mapping. Used as a reference, not displayed on the tax maps.
rd = roads layer. Used as a reference, not displayed on the tax maps.
sl = sublots layer showing subdivision bondaries.
ss = tax map section boundary.
zz = land hooks, showing the continuation of a parcel across a road or section map boundary for instance.

There are also:
fd = fire district boundaries
lx = historical annotation layer. Used as a reference, not displayed on the tax maps.
sc = school district boundaries
tb = town boundaries
vb = village boundaries
wd = water district boundaries


(13) Question: The RFP states that "RPTS is requesting that vendors submit, in addition to the cost proposal, an example of the work to be performed using the study area data provided with this RFP". Are you wanting just a sample of the digital parcel data or are you also wanting a PDF of an actual tax map complete with legend, tables, etc..?


Response: We are only requesting a sample of the digital parcel data. Please feel free to submit examples of tax maps your company may have prepared for other clients.

(14) Question: Does the county anticipate migrating to an ArcView, ArcEditor, or ArcInfo level license? (relationship and topology classes require at least an ArcEditor level license)

Response: We have an ArcInfo level license.

(15) Question: Orthorectification is generally associated with the modification of imagery to remove distortion caused by camera tilt and terrain relief. In what way do you anticipate the selected vendor to orthorectify the vector tax parcel data?

Response: The map data is meant to work with orthorectified imagery. We are requesting a spatial adjustment so that the layers are in the same system.


(16) Question: Did you need the roads layer converted as well? The proposal lists the following layers to be delivered:

Parcels, annotation, common ownership, sub-lots, block limit lines, section boundaries

Great lots, school districts, fire districts, water districts, municipal boundaries, hydrographic data.

Since roads are not specifically mentioned, I wanted to make sure you did not need them.

Response: We do not need the road layers converted as that information is included in the annotation layer.


(17) Question: I am assuming that you would want us to keep miscellaneous lines in addition to the rest of the layers, correct? By miscellaneous lines I meant leader lines, block number circles, road extensions, etc.

Response: Yes, please.
