Spatial :: Sdo_nn To Fetch Points From Point Cloud And Georaster
Mar 9, 2013
I have a requirement to fetch the nearest neighbor from a given point coordinates inside a point cloud/georaster data. how can i retrieve a collection of all neighboring points from a given point.
I guess i will have to use sdo_nn operator. how to use the operator to achieve the result.
I have data in point cloud (x,y,z,a,b,c,d (a,b,c,d are some attributes about this point)). i create a point cloud (sdo_pc - geometry), block tables (sdo_geometry - geometry). if i use a function to_geometry, result is only in multi point without attributes. it is way display this 3D data, and at the same time inquire of concerning for a attributes in concrete points?
I see that I can use SDO_LRS.SPLIT_GEOM_SEGMENT to split a line at a single point (and get 2 resulting lines).
However, how I could split a line, at multiple points, into multiple segments? I need to do this for many rows, therefore a function or procedure would be good if any exists.
I have loaded shape files with SQL developer Georaper and limited number of decimals to 8. There is option to limit number of decimals in georapter.But there are some X, Y with many decimals. This may create problem in spatial functions in which geometries are compared and filtered
how to control the decimal points of X,Y to be loaded in geometry column. -0.4695623500000000172249770002963487058878 51.47160360000000167701728059910237789154-0.4702653600000000211345252409955719485879 51.47174944999999723904693382792174816132-0.4713475400000000092859409051015973091125 51.47330664999999783049133839085698127747-0.4717886499999999760923685698799090459943
I'm trying to get the values of a Geometry which is an Oriented Point. To that, i'm using SDO_UTIL.GETVERTICES, but this utility only obtains the point X,Y, it doesn't obtain the values of the orientation vector.
The Geometry is this: MDSYS.SDO_GEOMETRY( 2001,8307,NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1,1,1,3,1,0), MDSYS.SDO_ORDINATE_ARRAY(-75.586088632813272,6.1794352615514194,0.57278169530235967,-0.81970795380217887,0) )
The query is this: SELECT c.ipid, c.nombre, t.X, t.Y, t.Z, t.W FROM Hidrantes c, TABLE(SDO_UTIL.GETVERTICES(c.geometria)) t where c.ipid = 4691117 ORDER BY c.ipid, t.id;
I am testing the Oracle Cloud in a trial mode.. I have created the Oracle user and would like to restore my existing (non Oracle Cloud) database from the standard DMP file (import dmp). In all references that I could find [URL}... and that was given to me by the Oracle Cloud support service I couldn't find the definite answer on a simple question: if I have a DMP file of my own database, can I and if yes, then how I can import this DMP file to my new Oracle Cloud database? some link on "step by step" instruction, if such exists. If there is no such a way, then what way should I use?
I followed the "Loading data into your database cloud service from SQLDeveloper" tutorial, and I cannot upload a table that contains a column of type SDO_GEOMETRY. I get an error message that reads: "Unsupported Cart Object: Unable to deploy some objects to the cloud. These objects have been deleted from inclusion. Review Cart contents before redeploying. The following have an unsupported data type: SPATIAL.FLIGHT_TRACK." I can load any table that does not contain a n SDO_GEOMETRY column.
1. I have for example my-custom-domain.com and want that my customers use this domain to login at APEX Application at Oracle Cloud. I don't want that my customers see
[URL]........
and see instead of my-custom-domain.com :)
How I can do it? Don't find any technical information about it...
2. Can I use my ssl certificates for my domain for Oracle Cloud Instance?
I can configure in trial account interactive report for print but Print attribute section contains message: Report printing is currently not available, there is no print server configured.It will be possible to use this option in non-trial version? If yes which type of print server is configured in this version (FOP or BI Publisher)?
As you know, Oracle Cloud runs Apex 4.1..In my premises I am running Apex 4.2...Normally, we cannot import apps exported from apex 4.2 into Apex 4.1. I am planing to move to Oracle Cloud... Can I import Apex app, which were exported from apex 4.2, into Oracle Cloud ??
If it is not compatible, then that means, I cannot move to the cloud now. When can I expect Oracle Cloud to upgrade to APEX 4.2 ??
I would like to develop an APEX cloud app locally and offline (my PC). Later, I'll deploy it to the cloud for testing when finished. I understand that the APEX/DB in the cloud only provides a sub-set of the features of a local APEX/DB installation. To make sure I develop a solution that will run in the cloud and not depending on features not supported, I would like to set up my local PC with the same limitations as the cloud instance. Is there a script/patch etc. that can be run to limit local features (or privs to them) to mimic the same premises and enviroment as when running in the cloud? (I know such exists for MS Azure local development).
I have a road network which is shape file format and i want to export it to oracle spatial format using any free tool, I am using arcgis 9.3.1 and Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bi,
I am working on a project that will require both projected coordinates and geographic coordinates for different product files coming in. I have no issues defining, storing, extracting or matching the geographic coordinates. My columns for those coordinates with SRID 8307 are defined in the user_sdo_geom_metadata table as follows:
the index: create index "MYDB"."INVGEO_IDX" on "MYDB"."INVENTORYGEOMETRY"("INVGEO") indextype is MDSYS.SPATIAL_INDEX;
how I am going to have a column that has both Geographic and Projected coordinates. Am I allowed to define more SDO_DIM_ELEMENT(s) fro the SDO_DIM_ARRAY with different min/max values. As an example, would I be able to still use an SRID of 8307 for both WGS 84 and GRS80 data (ellipsoid), something like the following:
Is that possible or do i have to create a new column in the database? Also, I don't know the relationship between the SDO_ELLIPSOIDS table and the SDO_GEOMETRY table.
how I'm going to make this work for both the geographic and projected coordinates or if I'm going to be able to make it work.
FRM-40501: ORACLE error: unable to reserve record for update or delete.
ORA-24374: define not done before fetch or execute and fetch
My master-detail form has single canvas. For both blocks, master and detail, two tables joined together in each. One table to be updated, second table has some info for reference (query only).
I am getting these errors when in detail block the item from LOV is selected for existing record. This does not happen for new record inserted in detail block.
Is there a way I can generate a list of date using a simple SELECT statement to generate all dates between to date points? For example between SYSDATE AND SYSDATE-7?
One way I know is have a table and run PL/SQL script to put all dates in it and query that but was wondering if it can be achieve via SQL SELECT query at all without creating a table (querying DUAL).
Table D-7 shows a hierarchical file mapping of a sample OFA-compliant installation with two Oracle home directories and two databases. The database files are distributed across three mount points, /u02, /u03, and /u04. URL....
why three mount points (/u02, /u03, and /u04) for datafiles? don' understant this. isn't it better to store all datafiles in one mountpoint?
I'm developing, or trying, on Apex 4.2...The issue is about themes and how to manage the positions of diferents Display Points of a theme.
Everybody know that any theme have a map where its position all differents parts of this map (Body1, Body2, Body3, position01, position02 and so). So when you choice any theme, it come with all this Display points defined. You can see this map rendering any region page and in the item Display Point you can see this map clicking on the light.
There is anyway to can manage this map and change position or behavior of those points?. For example , I'm interested that under the tabs, to have at the same height, 3 diferentes position, one at left, one at center and other at right.
have created a cart in SQL Developer with all the tables from HR schema. If I apply the cart to my database cloud service the tables and data are there but most of the constraints are missing.
Error report: SQL Error: ORA-02270: no matching unique or primary key for this column-list 02270. 00000 - "no matching unique or primary key for this column-list" *Cause: A REFERENCES clause in a CREATE/ALTER TABLE
I am really wondering about data loading to the cloud, I've just read the documentation, but regarding the packages, I have more than 100 package and I have to "add to cart" one by one the problem is that the package body is not added by default, so you have to expand the packages one by one then select the package body right click and add to cart. This task is very tedious, is there any other options.”
